The Peterson olefination of acylsilanes 1 by silylated carbanions 5,14 to give alkenes 13,17 via a 1,3-silyl shift is favored by the stabilization of the carbanion intermediate 16 through two sulfide units versus one as in 12, while a combination of DMPS on 1 and TBS on 14 leads to 1,2-migration product 15.
