Heck reaction - Wikipedia
The Heck reaction (also called the Mizoroki–Heck reaction) [1] is the chemical reaction of an unsaturated halide (or triflate) with an alkene in the presence of a base and a palladium catalyst to form a substituted alkene. It is named after Tsutomu Mizoroki and Richard F. Heck.
Heck Reaction - Organic Chemistry Portal
The palladium-catalyzed C-C coupling between aryl halides or vinyl halides and activated alkenes in the presence of a base is referred as the "Heck Reaction". Recent developments in the catalysts and reaction conditions have resulted in a much broader range of donors and acceptors being amenable to the Heck Reaction.

2023年6月30日 · The Heck reaction is a famous chemical reaction discovered by Mizoroki and Heck in 1972 through independent research. It involves the cross-coupling reaction between organohalides and alkenes, these two substances react in the presence of a palladium catalyst and a base to form a substituted alkene:
Heck Reaction - Description, Mechanism, Variations, Applications
Heck reaction is an organic chemical reaction in which an unsaturated halide reacts with an alkene in the presence of a palladium catalyst and a base. The reaction yields a substituted alkene and is considered to be a coupling reaction.
Heck Reaction: Mechanism, Applications, Limitations - Science Info
2024年4月28日 · The Heck reaction is a cross-coupling reaction between an organohalide and an alkene that produces a substituted alkene with palladium as a catalyst and base. It is an effective method for forming carbon-carbon bonds.
Variation of reaction conditions can greatly influence exo versus endo selectivity in small rings. Early examples of dehydrogenative processes did not employ oxidants and were stoichiometric in palladium.
Heck Reaction - an overview | ScienceDirect Topics
The “Heck reaction” (also called the Mizoroki–Heck reaction) is the chemical reaction of an unsaturated halide (triflate) with an activated alkene in the presence of a base and a palladium (Pd) species as catalyst to generate a substituted alkene.
Heck Reaction: Definition, Example, Mechanism, & Application
The Heck reaction (also called Mizoroki-Heck reaction) is a cross-coupling reaction of an organohalide with an alkene to make a substituted alkene using palladium as a catalyst and a base. It has drawn much attention due to high efficiency and simplicity.
