摘要：
Triphenylsilylzinc compounds stabilized by an N-heterocyclic carbene, [Zn(SiPh3)(2)(IMes)] (2) and [ZnX(SiPh3)(IMes)] [X = Cl (3a), Br (3b), I (3c)] [IMes = 1,3-Bis(2,4,6-trimethylphenyl)imidazole-2-ylidene], were synthesized by transmetalation from [ZnX2(IMes)(THF)(0-1)] [X = Cl (1a), Br (1b), I (1c)] and [LiSiPh3(THF)(3)]. According to single-crystal X-ray diffraction, [Zn(SiPh3)(2)(IMes)] (2) shows a trigonal-planar coordinated central zinc atom, whereas [ZnCl(SiPh3)(IMes)(THF)] (3a-THF) shows a distorted tetrahedral coordination.
