CuI-functionalized halloysite nanoclay as an efficient heterogeneous catalyst for promoting click reactions: Combination of experimental and computational chemistry
No full text Amine-functionalized
halloysite nanotubes (HNTs-2 N) were prepared and further modified by introduction of salicylaldehyde
and formation of imine functionality (HNTs-2 N-Sal). The latter was
subsequently used for immobilization of CuI and formation of
CuI@HNTs-2 N-Sal, which could effectively promote click reactions of
terminal alkynes, sodium azide and α-haloketones or alkyl halides in aqueous
media and under mild reaction conditions to afford 1,2,3-triazoles in
relatively short reaction times. Notably, the catalyst could be recycled in up
to six reaction runs with negligible loss of catalytic activity and CuI
leaching. Also, the geometry of CuI adsorption on the modified HNTs surface was
explored by molecular simulation with density functional theory. Furthermore,
topographic steric maps of possible coordination modes were obtained using the
recently released SambVca2 web application tool. Based on obtained results, a
catalytic site with superior performance was suggested.</p

Prostate glands (Fig. 1 D, pr) small, attached to ental portion of atrium by short stalk. Soft part of penis (Fig. 1 D, pe) cylindrical, about 75 µm long, 65 µm in diameter, enclosed in copulatory sac; penis surrounded by thin cuticularized, somewhat thimble-shaped sheath (Fig. 1 H, ps; Fig. 1 I), 80 µm long, 68 µm wide, with 5 µm thick walls.

Freshwater lake, 97–113 m depth, water temperature lower than 14 ºC, fine clay. Remarks: Judging from the long vasa deferentia, long tubular atria each with a small prostate gland, penes with distinct cuticular sheaths, and the atria longer than vasa deferentia, the new species fits the definition of Varichaetadrilus Brinkhurst, 1981. Nine species were previously known in the genus, all distributed in the Holarctic region (Timm, 2006). Among the known members of Varichaetadrilus, there are two species with spermathecal vestibules: V. pacificus (Brinkhurst, 1981), originally known from Washington, USA (Brinkhurst, 1981), and V. fulleri Brinkhurst & Kathman, 1983 recorded only from Kentucky, USA (Brinkhurst & Kathman, 1983). However, V. vestibulatus n. sp. is easily separated from those two species by the modified spermathecal chaetae and the shape of penial sheaths (Table 2). In addition, the spermathecal duct of the new species has pear-shaped middle vestibule, but V. p a c i f i c u s has cervix-like ental vestibule, and V. f u l l e r i has ectal vestibule. This is the first species of Varichaetadrilus recorded from China, and it is the lowest-latitude distributed member hitherto known in the genus. TABLE 2.

Prostate gland (Fig. 4 D, pr) large, attached to middle portion of atrium by short stalk. Atrial duct (Fig. 4 D, ed) curved, about 54 µm long, 25–36 µm wide. Soft part of penis (Fig. 4 D, pe) cylindrical, about 32 µm long, 20 µm diameter, enclosed in copulatory sac; penis surrounded by thin cuticularized, truncated-cone shaped sheath (Fig. 4 D, ps; Fig. 4 E), 116 µm long, 40–80 µm wide, one side of the ectal opening (Fig. 4 E, eo) curved upwards. Copulatory sac (Fig. 4 D, cs) 64 µm long, 40–50 µm wide. Spermathecal ampullae (Fig. 4 D, sa) oval to round, 105–125 µm in diameter, with sperm masses (Fig. 4 D, sm) in lumina, ducts (Fig. 4 D, sd) 160–250 µm long, 35–58 µm wide. Distribution and habitat: Known only from type locality, Yunnan Province, China. Freshwater lake, 5.0 m depth, water temperature 16 ºC, fine silt. Remarks: The genus Ilyodrilus consists of the type species, I. perrieri Eisen, 1879, together with I. templetoni (Southern, 1909) and the dubious entities I. frantzi Brinkhurst, 1965 and I. fragilis Eisen, 1879. The principal characteristics and the distribution of congeners are shown in Table 3. Ilyodrilus mesoprostatus n. sp. is distinguishable from congeners mainly in the respect that attachments of prostate glands are situated at middle part of the atria, while those of previously described species are all situated near the ental part of the atria (Table 3). The penial sheaths of different species are dissimilar. Despite the undeveloped type specimens, I. perrieri from California has more or less tubular, cuticular penial sheaths (Holmquist 1985). I. fragilis has thin sheaths (Eisen 1879; Brinkhurst 1978). The cosmopolitan I. templetoni has long conical tapering distally sheath with irregular opening (Brinkhurst 1965; Hrabĕ 1966) and I. frantzi has thin, truncated cone-shaped cuticular sheath (Brinkhurst 1965). The new species has truncated-cone shaped sheath, with ectal opening curved upwards at one side (Table 3). The presence of spermatozeugmata is regarded a diagnostic character of the genus Ilyodrilus (Brinkhurst & Jamison 1971). Although spermatozeugmata are absent in the present new species, it was assigned to this genus according to the structure of male genitalia. Spermatozeugmata are in fact not always present in Ilyodrilus. For instance, they were not mentioned in previous descriptions of I. perrieri and I. fragilis (Eisen, 1879; Holmquist 1985; Brinkhurst, 1965; Brinkhurst & Jamison 1971). Some specimens of I. templetoni have been described without spermathecae at all (Brinkhurst & Jamison 1971, Wang 2002), while for I. frantzi, the presence of spermatozeugmata was confirmed (Holmquist 1985). In the new species, I. mesoprostatus, the sperm were massed. So, the genus Ilyodrilus Eisen, 1879, needs a revision in the future.Published as part of Cui, Yongde & Wang, Hongzhu, 2009, Three new species of Tubificinae, Oligochaeta, from two plateau lakes in Southwest China, pp. 45-54 in Zootaxa 2143 on pages 51-53, DOI: 10.5281/zenodo.18861

Ventral chaetae bifid, (2) 4–6 per bundle anteriorly, 2–3 per bundle posteriorly, 60–160 µm long, 2–3 µm thick, upper tooth twice as long as lower (4 µm/2 µm), with (0) 1–2 fine intermediate teeth, nodulus distal (Figs. 4E,F, 5A–C). Ventral chaetae in X–XI present, unmodified. Male pores (Figs. 5G, 6C: mp) paired in line with ventral chaetae in anterior of X. Spermathecal pores (Fig. 5E: spp) paired in line with ventral chaetae, middle to posterior of XI. Chloragogen cells from VI onwards. Male genitalia paired in X–XII.

Atrium spindle-shaped, 560–640 µm long, maximally 80–100 µm wide (Figs. 5G, H, 6A: at). Ejaculatory duct 100–120 µm long, 20–32 µm wide, entering muscular bulb (Fig. 5G, H, 6A: ed; Fig. 5G: mb). Prostate gland large, attached to ental portion of atrium, 120–140 µm long, 80–100 µm wide (Fig. 5G, H, 6A: pr). Penis inconspicuous, surrounded by cuticular, symmetrical and funnel-shaped penial sheath. Penial sheath extremely thin, long and sinuous, 32–36 µm wide at ental end, 3–5 µm wide at thin and prolonged ectal portions, 520–540 µm long, length to width ratio nearly 15–16 (Figs. 5G, H, 6B: ps). Testes paired in X, immediately behind septum 9/10. Ovaries paired in XI, immediately behind septum 10/11. Spermathecae paired in X, ampullae oblong, 200–280 µm long, 140–250 µm wide; duct 100–120 µm long, 24–28 µm wide; sperm random in lumina, no spermatozeugmata (Figs. 5E, 6C: sp). Remarks. The main identification characteristics of long and winding vas deferens divided into thin and thick sections, long atrium gradually tapering towards distal portion, large prostate gland and elongate penial sheath suggest that the present species belongs to the genus Tubifex (Brinkhurst & Jamieson 1971; Holmquist 1985; Juget et al. 2006). Tubifex tubifex (Müller, 1774) resembles this species in pectinate dorsal chaetae, long and winding vas deferens divided into thin and thick sections, large prostates, and in atria with a long ejaculatory duct, but differs from it in a cylindrical penis covered with a short and tub-shaped cuticle ring. Furthermore, spermathecae are absent, or present with spermatozeugmata, or present with empty ampullae. T. gracilentus n. sp. is easily distinguished from its congeners by the extremely thin and long funnel-shaped penial sheath (Table 2). Distribution and habitat.

Holotype female mac., China, Heilongjiang Province, Greater Khingan, Nanwenghe national Nature Reserves (51°22.83'N, 124°34.24'E), 21.vii.2017, from grasses (Jun Wang). Paratypes: 1 female mac., 6 female mic., 1 male mic same data as holotype; Sanjiang Plain (45°01.08'– 48°27.93'N, 130°13.17'– 135°05.43'E), 7.vii.2017, 9 female mac., 6 female mic., 1 male mac. from grasses (Jun Wang); Mohe, Tuqiang town (52°56.85'N, 122°46.73'E), 21.vii.2017, 1 female mac., 4 female mic., 1 male mac., 4 male mic. from grasses (Jun Wang), same locality and habitat 1 female mac., 1 female mic., 1 male mac., 1 male mic., 12.viii.2018 (Jun Wang). Distribution. China (Heilongjiang). Etymology. The Latin word oroqeni derived from a minority of Oroqen Ethnic Group, who live in the type locality. Remarks. This new species is closely similar to the Japanese species A. ponokikirmui in having 9-segmented antennae, metanotum without campaniform sensilla and abdominal tergite VIII with complete posteromarginal comb and the microtrichia having wide bases. However, this new species can be distinguished as follows: abdominal tergite X yellowish (Fig. 45) but brown in A. ponokikirmui, tergites II–VII with lobes on posterior margin, but larger laterally (Fig. 39), in contrast to separated serrations in A. ponokikirmui.Published as part of Cui, Yanze & Wang, Jun, 2019, The genus Anaphothrips (Thysanoptera, Thripidae) in China, with three new species, pp. 246-258 in Zootaxa 4700 (2) on pages 253-255, DOI: 10.11646/zootaxa.4700.2.4, http://zenodo.org/record/354844
