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.
One of the
benefits of the Heck Reaction is its outstanding trans
Mechanism of the Heck Reaction
Trifunctional N,N,O-terdentate amido/pyridyl carboxylate Pd(II) complexes
were highly active and stable phosphine-free catalysts for Heck and
room-temperature Suzuki reactions with high turnover numbers.

A palladacycle phosphine mono-ylide complex is as an efficient catalyst for
the Mizoroki-Heck cross-coupling reaction of aromatic or aliphatic olefins with
a broad range of aryl bromides and chlorides. The reactions proceeded in good
yields in the presence of low loadings of palladium (10 ppm) under aerobic
conditions. High catalyst activities with turnover frequencies of up to 20,000 h-1
were observed at 130°C.

An efficient and simple protocol for phosphine-free Heck reactions in water in
the presence of a Pd(L-proline)2 complex as the catalyst under
controlled microwave irradiation conditions is versatile and provides excellent
yields of products in short reaction times. The reaction system minimizes costs,
operational hazards and environmental pollution.
