Stereoselective synthesis of various (E)- and (Z)-2-alkenyltrimethylsilanes (RCH=CHCH2SiMe3; R=Me, Et, n-Bu, i-Pr, c-hexyl, t-butyl, and phenyl) has been accomplished by a reaction of 1,2-epoxy-1,3-bis(trimethylsilyl)propane with Grignard reagents (RMgX) followed by subsequent Peterson olefination reactions of resulting 1,2-bis(trimethylsilyl)-3-alkanols ; the acid (BF3OEt2 or HClO4)-catalyzed olefination yields the (E)-isomer, while the base (KH or NaH)-induced olefination yields the (Z)-isomer in more than 95 percent stereochemical purity in most cases.

1,2-Epoxy-1,3-bis(trimethylsilyl)propane reacts with various Grignard reagents (RMgX) to give 1-R-2,3-bis(trimethylsilyl)-1-propanols which upon olefination with NaH or with BF3Et2O give the corresponding (Z) or (E)-2-alkenyltrimethylsilanes in moderate t
