Abstract
Abstract Trisubstituted olefins are easily accessible under mild reaction conditions using a new catalyst system consisting of dicyclohexylamine or methyl (dicyclohexyl) amine and a phase-transfer catalyst (see equation). The choice of the base was found to be crucial for the stereoselectivity and the rate of Heck type arylation reactions.
