A mild preparation of vinyliodides from vinylsilanes
摘要:
A new method for the synthesis of vinyliodides from vinylsilanes is presented. Using N-iodiosuccinimide in acetonitrile or acetonitrile/monochloroacetonitrile, this transformation is cleanly effected at room temperature under virtually neutral conditions. Copyright (C) 1996 Elsevier Science Ltd
Synthesis of (Z)-Vinylsilanes with High Diastereoselectivity by Using Samarium Diiodide
摘要:
[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.

The in situ generated (chlorolithiomethyl)trimethylsilane reacts at - 60°C to - 45°C with different aldehydes or ketones 1 to afford, after lithiation with lithium naphthalenide at - 78 °C to 20 °C, vinylsilanes 5a-b in a stereoselective manner.
