Abstract
Reaction of two equivalents of ((CH3)3Si)2C(C6H5)SLi·3THF with SnCl2·IPr (IPr=:C[N(Diip)C(H)]2, Diip= 2,6 i‐(CH3)2CH(C6H5) led to fragmentation of the organolithium component and gave IPr·Sn(SPh)2, compound 3. The latter compound has been further prepared from Ph‐SSi(CH3)3 whereas disproportionation of the Sn(II) species was observed when starting from Ph‐SLi. Stannylene adduct 3 has been characterized spectroscopically and its structure was explored with single crystal X‐ray diffraction (SCXRD). The carbene donor in 3 can be displaced by chloride upon formal HCl addition giving rise to the ionic stannylene adduct 3a IPr+[SnCl(SPh)2]‐, the structure of which was investigated with SCXRD as well.
