ChemInform Abstract: An Efficient Approach to gem‐Difluorocyclopropylstannanes via Highly Regio‐ and Stereoselective Hydrostannylation of gem‐Difluorocyclopropenes and Their Unique Ring‐Opening Reaction to Afford β‐Fluoroallylic Alcohols.

Abstract

Alcohols. -Compound (VIg) undergoes ring-opening reactions with water, alcohols, carboxylic acids and amides as nucleophiles. The use of amines or thiols as nucleophiles gives no comparable ring-opened products. -(NIHEI, T.; HOSHINO, T.; KONNO*, T.; Org. Biomol.
