The reaction of [Ge{N(SiMe3)C(Ph)C(SiMe3)(C5H4N-2)}Cl] (1) with LiBut or LiC⋮CPh in Et2O
afforded substituted products [Ge(R){N(SiMe3)C(Ph)C(SiMe3)(C5H4N-2)}] [R = But (2) or C⋮CPh (3)],
respectively. However, the one-pot reaction of 1 with PhC⋮CH and BunLi in Et2O afforded lithium
germinate [{(PhC⋮C)3Ge}3GeLi(Et2O)3] (4). Compound 1 can also undergo ligand transfer reaction with
LiAlH4 to give [AlH{N(SiMe3)C(Ph)C(SiMe3)(C5H4N-2)}2] (5). Treatment of 1 with excess NaBH4 in
THF afforded germanium(II) hydride-borane adduct [Ge(BH3){N(SiMe3)C(Ph)C(SiMe3)(C5H4N-2)}H]
(6). The reaction of 1 with MI (M = Cu and Au) gave the first examples of Ge(II)−M(I) adducts [Ge(CuI){N(SiMe3)C(Ph)C(SiMe3)(C5H4N-2)}Cl]4 (7) and [Ge(AuI){N(SiMe3)C(Ph)C(SiMe3)(C5H4N-2)}Cl] (8). Compounds 2−8 have been characterized by X-ray analysis.
The reaction of pyridyl-1-azaallyl germanium(ii) chloride RGeCl () [R = {N(SiMe(3))C(Ph)C(SiMe(3))(C(5)H(4)N-2)}] with lithium metal afforded the dimeric germanium(i) compound [(RGe)(2)] (); compound reacts with an excess of elemental sulfur to afford the novel germanium analogue of a dithiocarboxylic acid anhydride [{Ge(S)R}(2)S] () 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
