Hydrozirconation of alkynyl(phenyl)iodonium salts and stereoselective synthesis of (E)-trisubstituted olefins
Abstract
Hydrozirconation of alkynyl(phenyl)iodonium salts affords alkenylchlorozirconocenes with the Zr-C bond germinal to the iodonium moiety, and two subsequent substitution reactions proceed with retention of the configuration of the carbon-carbon double bond.
