The stereoselective β-C(sp2)–H arylation of various acyclic enamides with arylsilanes via Rh(III)-catalyzed cross-coupling reaction was illustrated. The methodology was characterized by extraordinary efficacy and stereoselectivity, a wide scope of substrates, good functional group tolerance, and the adoption of environmentally friendly arylsilanes. The utility of this present method was evidenced by

A method for hydrosilylating a vinyl-substituted aromatic compound comprising reacting a hydrido (hydrocarbonoxy)silane compound with the vinyl-substituted aromatic compound in the presence of a platinum or platinum compound catalyst and a carboxylic acid. The presence of the carboxylic acid increases the positional selectivity of addition in the hydrosilylation reaction and reduces the polymerization of vinyl groups even in the case of a high-temperature or long-term hydrosilylation reaction.

first example of nickel-catalyzed monofluoroalkylation of arylsilanes has been developed with readily available fluoroalkyl halides. This novel transformation has demonstrated high reactivity, broad substrate scope, excellent functional group tolerance, and mild reaction conditions. The selective activation of a relatively inert C–Si bond for slow release of aryl carbanion is the key reason for reducing

copper-catalyzed directarylation. Readily available and structurally simple aryl precursors such as arylboronicacids, aryl trialkoxysilanes and dimethyl-aryl-sulfonium salts were used as the source for the aryl substituents. The scope of the reactions was tested, and the reactions were insensitive to the electronic nature of the aryl groups, as both electron-rich and electron-deficient aryls were successfully
The first cross‐coupling reaction between aryl silanes and aryl boronic acids is described. This transformation represents one of the very few examples of coupling reactions between two nucleophilic organometallic reagents and provides a new method for the formation of biaryl compounds. The successful development of this reaction was enabled by the use of commercially available 2,2′‐bis(diphenylphosphino)‐1
