Heck Reaction
... For intermolecular Heck reactions with neutral Pd complexes and unactivated or electron-poor alkenes, the regioselectivity for R' insertion is under steric control, resulting in substitution at the less sterically hindered position. In contrast, with neutral Pd complexes and electron-rich alkenes (e ...
