Abstract

The reaction of pyridyl-1-azaallyl germanium(II) chloride RGeCl (1) [R = {N(SiMe3)C(Ph)C(SiMe3)(C5H4N-2)}] with lithium metal afforded the dimeric germanium(I) compound [(RGe)2] (2); compound 2 reacts with an excess of elemental sulfur to afford the novel germanium analogue of a dithiocarboxylic acid anhydride [{Ge(S)R}2S] (4) via the insertion of elemental sulfur into the Ge(I)–Ge(I) bond followed by the oxidative-addition of elemental sulfur to the germanium(II) centres.
