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.
