Hydrocarbonylation of Aryl Halides

Palladium-catalyzed hydrocarbonylation of aryl and vinyl haUdes or triflates is a weU known reaction used as a key step in the synthesis of complex biologically active molecules. The aryl and vinyl halide or triflate is converted into the 

The available information about supported metals as catalysts for Michael reactions will be commented upon, with emphasis on selected silica supports [93].
