IPy2BF4 is also a useful reagent for stereospecific iodine-silicon exchange in open chain trimethylsilylalkenes
摘要:
Reaction of the title monosubstituted vinylsilanes with IPy(2)BF(4)/HBF4 gives iodoalkenes through the ipso-substitution process with stereospecific retention of configuration.
(Diiodomethyl)trimethylsilane (Me3SiCHI2, 1) is produced by treatment of iodoform with manganese in the presence of Me3SiCl. Aldehydes are converted to (E)-1-trimethylsilyl-1-alkenes in a stereosel...

[GRAPHICS]Beta-Elimination of O-acetyl 1-chloro-1-trimethylsilylalkan-2-ols 1 was achieved by using samarium diiodide as a metaling reagent and afforded the corresponding (Z)-vinylsilanes with high stereoselectivity. The starting compounds 1 were easily prepared by treatment of different aldehydes with (chlorolithiomethyl)trimethylsilane and further acetylation.
