ChemInform Abstract: A Remarkable Regiocontrol in the Palladium‐Catalyzed Silylstannylation of Fluoroalkylated Alkynes — Highly Regio‐ and Stereoselective Synthesis of Multi‐Substituted Fluorine‐Containing Alkenes.

Abstract

Alkenes. -The Pd-catalyzed silylstannylation of fluorine containing internal alkynes (I) affords the corresponding adducts (III)/(IV) in a cis-selective manner in good to high yields. Two regioisomers can be prepared selectively by using appropriate Pd-catalysts. -(KONNO*, T.; KINUGAWA, R.; ISHIHARA, T.; YAMADA, S.; Org. Biomol.
