    Description / Table of Contents: Tris(trimethylsilyl)methaneselenenyl Halides and Chalcogenides.Ditrisyldiselenide (1) (trisyl = TSi = (Me3Si)3C) reacts with SOCl2, Br2 and I2 to provide trisylselenenyl halides TSiSeX (2: X = Cl; 3: X = Br, 4: X = I). Insertion of S and Se into the Se—Se bond of 1 to yield (TSiSe)2Sn (5: n = 1; 6: n = 2) and (TSiSe)2Sen (7: n = 1; 8: n = 2) was catalysed by iodine. 5 was isolated in pure state and examined by X-ray diffraction. Triselenide 7 can be cleaved by I2 in CS2 to give 4 and Se2I2 (9). From 2 with Me3SiCN and Me3SiNCS, the new selenenyl pseudohalides TSiSeCN (10) and TSiSeSCN (11) were prepared. The compounds were characterised by 1H, 13C- and 77Se n.m.r. spectra.
    Notes: Ditrisyldiselenid (1) (Trisyl  -  Tsi  -  (Me3Si)3C—) reagiert mit SOCl2, Br2 und I2 zu Trisylselenenylhalogeniden TSiSeX (2: X = Cl; 3: X = Br, 4: X = I). Die Einschiebung von Schwefel und Selen in die Se—Se-Bindung von 1 zu (TSiSe)2 Sn (5: n = 1; 6: n = 2) bzw. (TSiSe)2Sen (7: n = 1; 8: n = 2) läßt sich mit Iod katalysieren. 5 wurde in reiner Form isoliert und durch Röntgenstrukturanalyse untersucht. Das Triselenid 7 wird durch Iod in CS2 zu 4 und Se2I2 (9) gespalten. Aus 2 lassen sich mit Me3SiCN bzw. Me3SiNCS das Trisylselenocyanat TSiSeCN (10) bzw. Trisylselenenylthiocyanat TSiSeSCN (11) gewinnen. 1H, 13C- und 77Se-NMR Spektren von 1 - 11 sind im Einklang mit den Strukturvorschlägen.

    Description / Table of Contents: Organoarsenic-bridged Stannio ComplexesThe new pentacarbonyl(di-tert-butylarsinochlorostannio)chromium(0) and wolfram(0) complexes (CO)5MSnClAsR2 (M = Cr, W; R = t-C4H9) have been obtained from the reactions of the corresponding thf-containing tin dichloride complexes with di-tert-butyl(trimethylsilyl)-arsine. Infrared, Raman, and 119mSn-Mössbauer data are discussed in terms of di-tert-butyl-arsinobridged stannio-complex-type structures.

    Description / Table of Contents: Organophosphine-substituted Halogenogermylenes and -stannylenesHalogeno(di-tert-butylphosphino)germanium(II) and -tin(II) [(CH3)3C]2PMX (M = Ge, Sn; X = Cl, Br) are obtained by the reactions of triphenylphosphinedichloro- and -dibromogermylene, tindichloride and tri-tert-butylphosphinedibromostannylene with equimolar amounts of di-tert-butyl(trimethylsilyl)phosphine with elimination of chloro- and bromotrimethylsilane.
