摘要
Syntheses of NHC adducts of bis[tris(trimethylsilyl)silyl]germylene and -stannylene and some structurally related cyclic disilylated stannylenes are reported. Reactions of a cyclic stannylene NHC adduct with gold and silver cyanide led to cationic metal complexes with two cyanostannyl ligands. The Ag complex decomposed further to a cyanostannide. Reactions of bis[tris(trimethylsilyl)silyl]germylene and -stannylene NHC adducts with gold and silver cyanide displayed more unusual coordination chemistry with one silyl group of the ylene unit being transferred to the group 11 metal.
