The mechanism is to be writtenfor the given Heck reaction. that can explain the final stereochemistry and the Pd species, which can promote the reaction to go to completion inonly catalytic quantites. Concept introduction: The Heck Mizoroki reaction is a coupling reaction between an alkene and an alkenyl or aryl halide in the presence of a palladium catalyst and a base, usually an amine , at an elevated temperature. The active palladium catalyst is involved in the reaction. This is so because the catalyst has only two ligands. Hence, it is coordinatively unsaturated.
