摘要

The organotin reagents [2-PyC(SiMe3)(2)SnR3] (R = Me, Bu-n) were prepared in good yields from the reaction between the lithium salt of 2-bis(trimethylsilyl)picoline and the corresponding trialkyltin chlorides. Reactions of these organotin reagents were carried out with various Pd and Pt complexes including [MCl2(cod)] and [MCl2(PhCN)(2)] (M = Pd Pt). The results show that a Me group is transferred to the metal atom, rather than the 2-bis(trimethylsilyl)picolyl group. The mechanism for this reaction is discussed and reasons why Me group transfer occurs based oil DFT computed structural data are given.
