system was applied successfully to SuzukiMiyaura couplings of some arylchlorides and to the MizorokiHeck as well as the Sonogashira reaction showing relatively high activities and good selectivities. Like with other ligand‐free supported systems, the reaction proceeded dominantly by a homogeneousmechanism, but attack of an aryl iodide to Pd‐nanoparticles can be excluded as substantial contribution

A practical method for heterogeneously-catalyzed Mizoroki–Heck reaction: Flow system with adjustment of microwave resonance as an energy source
The microwave-assisted and continuous-flow Mizoroki–Heck reaction using a heterogeneous palladiumcatalyst supported on the anion-exchange resin DIAION WA30 (7% Pd/WA30) is described. The microwave resonance is finely adjusted to 2.4 GHz according to the electric permittivity of the reaction medium for efficient heating. Organic solvents, such as acetonitrile, N,N-dimethylacetamide, and toluene, can

Palladium‐catalyzed cross‐coupling reactions of various aryl sulfinic acidsalts with a wide variety of vinyl substrates have been achieved in good to excellent yields under simple aerobic conditions at 70°C with the assistance of Cu(II) salts. The reaction can be accelerated by the combination of DMSO with THF. The reported Matsuda–Heck type coupling reactions are tolerant to the common functional

Arenes and electron‐deficient olefins can be oxidatively coupled through a biomimetic Pd(OAc)2‐catalyzed transformation. CH activation of the arene partner is effected under reaction conditions of low catalyst loading, normal oxygen pressure, and using p‐benzoquinone and iron phthalocyanine as electron‐transfer mediators (ETMs). By controlling catalyst loading, the reaction can be made selective for
