The Spoken Wikipedia Corpora
No full textThe Spoken Wikipedia project unites volunteer readers of Wikipedia articles. Hundreds of spoken articles in multiple languages are available to users who are – for one reason or another – unable or unwilling to consume the written version of the article. Our resource, the Spoken Wikipedia Corpus, consolidates the Spoken Wikipediae, adding text segmentation, normalization, time-alignment and further annotations, making it accessible for research and fostering new ways of interacting with the material.

Angewandte Chemie. 2020;132(40):17541-17545.Die Reaktion des geminalen frustrierten Lewis-Paares (F5C2)3SnCH2P(tBu)2(1) mit N-Sulfinylanilin PhNSOergab das erste Schwefelmonoxid-Addukt eines Hauptgrup-penmetalls (F5C2)3SnCH2P(tBu)2·SO (2). Es enthält einenSnCPSO-Ring. Das zweite Produkt ist ein Phenylnitren-Addukt von1. Die überraschende Stabilität von2wurde mitdenen der bisher unzugänglichen O2- und S2-Addukte von1verglichen. Versuche, diese aus1und den elementarenChalkogenen (O2,S8,Se1,Te1) herzustellen, führten zu vier-gliedrigen SnCPE-Ringsystemen.

No full textArt historian Timo de Rijk was appointed Professor of Design, Culture and Society in Delft and Leiden last September. He calls this combination ‘a real breakthrough’. ‘Leiden University studies the workings of culture, while TU Delft aims at creating new things. These are fundamentally different approaches. I am the bridge between the two.’Industrial Design Engineerin
Solid-state molecular structures of Se(IV) and Te(IV) dihalides X2Se(CH3)(C6F5) and the gas-phase structure of Se(CH3)(C6F5)

Zeitschrift für Naturforschung B, Journal of Chemical Sciences. 2023.In a systematic study the Se(IV) and Te(IV) dihalides F2E(CH3)(C6F5), Cl2E(CH3)(C6F5) and Br2E(CH3)(C6F5) (E = Se, Te) have been synthesized and their crystal and molecular structures been investigated by X-ray diffraction and computational methods. The solid-state structures of all compounds show significant correlations between the lengths of the E-C1 bond and the intermolecular E & BULL;& BULL;& BULL;X (X = F, Cl and Br) contacts, indicating the presence of sigma-hole interactions. For comparison, the crystal and gas phase (electron diffraction) structures of Se(CH3)(C6F5) are presented as well. They show very similar structural parameters in both phases. The structures of the single molecules X2E(CH3)(C6F5) have been analyzed by quantum-chemical methods in terms of their surface potentials. They show significant similarities of their molecular electrostatic-potential topologies (V (s,max)). The magnitude of V (s,max) correlates with the aggregation pattern
Isolation of a Ge(I) Diradicaloid and Dihydrogen Splitting
No full textSharma MK, Ebeler F, Glodde T, Neumann B, Stammler H-G, Ghadwal R. Isolation of a Ge(I) Diradicaloid and Dihydrogen Splitting. Journal of the American Chemical Society. 2021;143(1):121–125.The cyclic Ge(I) compound [(ADCPh)Ge]2 (4) (ADCPh = {CN(Dipp)}2CPh, Dipp = 2,6-iPr2C6H3) containing a 6π-electron C4Ge2 framework has been isolated as a red crystalline solid. CASSCF calculations reveal a closed-shell singlet ground state for 4 with a considerable diradical character (y = 34%). Thus, the diradicaloid 4 readily splits dihydrogen at room temperature to yield the elusive bis-hydridogermylene [(ADCPh)GeH]2 (5)
An Adduct of Sulfur Monoxide to a Frustrated Sn/P Lewis Pair
No full textHoltkamp P, Glodde T, Poier D, Neumann B, Stammler H-G, Mitzel NW. An Adduct of Sulfur Monoxide to a Frustrated Sn/P Lewis Pair. Angewandte Chemie (International ed. in English). 2020;59(40):17388-17392.The geminal frustrated Lewis pair (F5C2)3SnCH2P(tBu)2 (1) reacted with N‐sulfinylaniline PhNSO to afford the first sulfur monoxide adduct of a main group metal, (F5C2)3SnCH2P(tBu)2⋅SO (2), which contains a SnCPSO ring. The second product is a phenylnitrene adduct of 1. The surprising stability of 2 was compared with the stabilities of the so far inaccessible O2 and S2 adducts of 1. Attempts to prepare these from 1 and the elemental chalcogens (O2, S8, Se∞, Te∞) led to four‐membered SnCPE ring systems. Quantum‐chemical investigations of 2 demonstrate the bond polarity of the SO unit to stabilize 2
A crystalline C5-protonated 1,3-imidazol-4-ylidene.

Chemical communications (Cambridge, England). 2020;56(13):2027-2030.The first C5-protonated 1,3-imidazol-based mesoionic carbene iMICBp (2) (iMICBp = :C{CH(NDipp)2C(Bp)}; Dipp = 2,6-iPr2C6H3; Bp = 4-PhC6H4) has been reported as a crystalline solid. Spectroscopic, X-ray diffraction, and computational studies clearly support the carbenic nature of 2, which has been further corroborated by its reactions with Ni(CO)4, (Me2S)AuCl, white phosphorus, and CO2
Synthesis of Bifunctional Boron-Lewis Acids - Thorough Investigation of the Adduct Formation with Pyrimidine
No full textRudlof J, Glodde T, Mix A, Neumann B, Stammler H-G, Mitzel NW. Synthesis of Bifunctional Boron-Lewis Acids - Thorough Investigation of the Adduct Formation with Pyrimidine. European Journal of Inorganic Chemistry . 2022: e202100842.Three bifunctional boron-Lewis acids based on a 1,2-diethynylbenzene backbone were synthesized using a tin-boron exchange protocol in good to very good yields. Complexation experiments with pyrimidine were thoroughly investigated using the example of 1,2-bis(benzo[d][1,3,2]dioxaborol-2-ylethynyl)benzene (3) in solution, in the solid phase and by quantum-chemical calculations. Two adducts were structurally investigated by X-ray diffraction experiments. DOSY-/VT-NMR experiments gave insight into the dynamic behaviour of the synthesized poly-Lewis acids with pyrimidine
