Abstract: A novel synthesis of styrene derivatives through decaroxylative olefination of potassium benzoates with alkynes using Pd2dba3/CuBr as catalyst system has been developed. The protocol proceeded smoothly and in most cases Z-alkene was the main product. Electron-rich potassium benzoates reacted more efficiently than those of electron-deficient substrates. Heteroaromatic and electron-deficient aryl alkynes were not consistent with this transformation. Graphical abstract: [Figure not available: see fulltext.].

Earlier studies have shown that the intermediate [C5Me5)Rh(PMe3)] reacts with both alkane and arene C-H bonds to give oxidative-addition adducts. In this paper, reactions of electrophiles with complexes of the type (C5Me5)Rh(PMe3)(R)H, where R = methyl, phenyl, and 2,6-xylyl, are discussed. While insertion into the metal-hydrogen bond results in the formation of a stable functionalized metal complex containing the alkane or arene, elimination of organic products is found to proceed only under oxidizing conditions.
