Oxidative Addition to a Monomeric Stannylene To Give Four-Coordinate Tin Compounds Containing the Bulky Bidentate Ligand C(SiMe3)2SiMe2CH2CH2Me
文摘
Reaction of (THF)2KRRK(THF)2 (RR = C(SiMe3)2SiMe2CH2CH2Me2Si(Me3Si)2C) with SnCl2in Et2O gave a mixture of the cyclic and linear SnII compounds RSnR, 4, and ClSnRRSnCl,9. This mixture was treated with MeI to give the corresponding SnIV compounds RSnMeIR,5, and IClMeSnRRSnMeClI, 10. Treatment of 5 and 10 with AgO2CCF3 gave the corresponding trifluoroacetates 6 and 11, which were structurally characterized.
