Reaction of Mg and Me3SiCl with Ph2SbCl or PhSbCl2 gives Ph2SbSiMe3 (1) or PhSb(SiMe3)2 (2).Sulfur inserts into 1 to give Ph2SbSSiMe3 (3).Products of action of S8 on 2 are 3, PhSb(SSiMe3)2 (4), (Me3Si)2S, and Sb2S3.Hydrolysis or methanolysis of 1, or 2 give Ph2SbH (5), or PhSbH2 (6), respectively.Key words: Diphenyl(trimethylsilyl)stibane; phenylbis(trimethylsilyl)stibane; diphenyl(trimethylsilyl-thio)stibane; diphenylstibane; phenylstibane.

Butylantimony(III) bromides react with Mg in tetrahydrofuran (THF) even in presence of Me3SiCl exclusively with Sb-Sb-coupling: Starting from Bu2SbBr, Bu2SbSbBu2 is formed and BuSbBr2 is reduced to (BuSb)x.Sb-Si-coupling dominates in the reactions of Ph2SbBr or t-Bu2SbCl with Mg/Me3SiCl/THF yielding Ph2SbSiMe3 or t-Bu2SbSiMe3.Both Sb-Sb- and Sb-Si-coupling reactions are observed, when PhSbBr2 reacts with Mg and Me3SiCl yielding PhSb(SiMe3)2 and (PhSb)x.The same reactants can also form the distibanes Ph2(SiMe3)2Sb2 and PhSb(SiMe3)3Sb2.The reaction of t-BuSbCl2 with Mg/Me3SiCl yields the stibines t-BuSb(SiMe3)2 and Sb(SiMe3)3 together with (t-BuSb)4.In the reactions of t-BuSbCl2 or PhSbBr2 the ratio of Sb-Sb- and Sb-Si-coupling can be strongly influenced by using different reaction conditions. - Keywords: Diphenyl(trimethylsilyl)stibine, Phenylbis(trimethylsilyl)stibine, Di-tert-butyl(trimethylsilyl)stibine, tert-Butyl-bis(trimethylsilyl)stibine
