Oxidative addition to a monomeric stannylene to give four-coordinate tin compounds containing the bulky bidentate ligand C(SiMe3)(2)SiMe2CH2CH2Me2Si(Me3Si)(2)C. Crystal structures of CH2Me2Si(Me3Si)(2)CSnC(SiMe3)(2)SiMe2CH2, CH2Me2Si(Me3Si)(2)CSnMe(O

摘要

Reaction of (THF)(2)KRRK(THF)(2) (RR = C(SiMe3)(2)SiMe2CH2CH2Me2Si(Me3Si)(2)C) with SnCl2 in Et2O gave a mixture of the cyclic and linear Sn-II compounds RSnR, 4, and ClSnRRSnCl, 9. This mixture was treated with MeI to give the corresponding Sn-IV compounds RSnMeIR, 5, and IClMeSnRRSnMeClI, 10. Treatment of 5 and 10 with AgO2CCF3 gave the corresponding trifluoroacetates 6 and 11, which were structurally characterized. [References: 37]
