헥 반응 (팔라듐 촉매 짝지음)

ArX + CH2=CHR → ArCH=CHR + HX

개요

The Heck reaction couples an aryl or vinyl halide with an alkene using a palladium catalyst and base. The mechanism involves oxidative addition of ArX to Pd(0), syn-migratory insertion into the alkene, and beta-hydride elimination to give the substituted alkene. Richard Heck shared the 2010 Nobel Prize.

일상 속 예시

The anti-inflammatory drug naproxen and the sunscreen ingredient octyl methoxycinnamate are synthesized using the Heck reaction.
