Synthesis and Characterization of NHC Stabilized Bis(phenylsulfanyl)stannylene

Reaction of two equivalents of ((CH 3 ) 3 Si) 2 C(C 6 H 5 )SLi ⋅ 3THF with SnCl 2 ⋅IDipp(IDipp=1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene) led to fragmentation of the organolithium component and gave IDipp⋅Sn(SPh) 2 , compound 3 . The latter compound has been further prepared from Ph‐SSi(CH 3 ) 3 whereas disproportionation of the Sn(II) species was observed when starting from Ph‐SLi. The 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 4 [IDippH] + [SnCl(SPh) 2 ] − , the structure of which was investigated with SCXRD as well.
