Gnomidolon pulchrum Martins 1960
No full textGnomidolon pulchrum Martins, 1960 (Fig. 2) Gnomidolon pulchrum Martins, 1960: 7; Monné, 2005: 313 (cat.). Martins (2006) called attention to the variation in color of G. pulchrum. The typical form, with the apical half of the elytra reddish, occurs in the south-central part of Paraguay (San Pedro, Cordillera) and in northern Argentina. The form with the apical half of the elytra black is recorded for Brazil (Mato Grosso), but also occurs in northern Paraguay (Concepción). The typical form has been illustrated in color by Martins (1967: 210, est. 7, fig. 2; 2006: 169, fig. 183). A female from Bolivia before us agrees with the form that shows the apical half of the elytra black, but the extremities of the elytra have a narrow transverse white stripe (Fig. 2). Structurally, the specimen agrees morphologically with the other forms cited. Specimens examined. BOLIVIA, Santa Cruz: Albanez (40 km S S(santa)C(cruz), “Laspetas”, fêmea, 6.XII. 2011, J. L.

Taiophlebia ferreirai Martins-Neto & Gallego & Brauckmann & Cruz 2007, comb. n.

Remarks: A. ferreirai from the Upper Carboniferous (Piedra Shotle Formation, Chubut) of Argentina, was originally attributed to the palaeodictyopterans but clearly exhibits characters typical for Taiophlebia, and can be therefore transferred to the latter genus.Published as part of Martins-Neto, R.

The reaction of [μ-N,N-Cu-(3,5(CF3)2pz]3 (1) with halide sources led to the formation of Cu(II) hexanuclear derivatives such as [(Cu((CF3)2pz)6(OH)6) X][Bu4N] (2a)(Cl-), (2b) (Br-), (2c) (I-), (2d) (NO2-).[1] If the reaction occurs in the same conditions but without halides, a highly hydrated hexanuclear metallocycle [(Cu((CF3)2pz)6(OH)6) (H2O)n], (3), was isolated, ruling out the template action of the anions. By replacing the CF3 groups with NO2 groups in the pyrazole, neither the trinuclear nor the hexanuclear copper derivatives were obtained, and the dinuclear [Cu-(3,5-(NO2)2pz)(PPh3)]2 compound, (4), was the only Cu(I) derivative isolated in good yield. Even though CF3 and NO2 are both withdrawing groups, a pronounced different chemical behavior was already revealed in the case of similar pyrazolate silver(I) derivatives.[2] All compounds were characterized by elemental analysis, NMR, IR spectroscopy and ESI-MS spectrometry. In the case of compound 4 its crystal structure has been determined by X Ray diffraction analysis, evidencing its dinuclear nature, build up by two bridging ligands which coordinate two copper atoms through nitrogen donors, forming a six member ring with boat conformation. Compounds (3) and (4) act as catalysts towards the microwave (MW) assisted peroxidative oxidation of cyclohexane to cyclohexanol and cyclohexanone under mild conditions, which is of industrial significance for the synthesis of Nylon-6,6. High yield (up to 51% of oxygenated products) is obtained after 2h of MW irradiation, using a maximum of 0.2% molar ratio of 3 (the best catalyst) relatively to the substrate in the presence of TEMPO. The efficiency of the catalytic systems as well as the influence of various parameters, such as the reaction time, amount of catalyst, temperature and presence of different additives, are discussed.
