A highly efficient Bi(OTf)3-catalyzed benzylation of arenes and heteroarenes has been developed. The mild reaction conditions, high yields, operational simplicity and practicability, broad scope, and remarkably low catalyst loading render this environment friendly process an attractiv approach to diarylmethane derivatives. The extension to an intramolecular variant of this procedure provides a valuable

A simple and efficient continuous-flow hydroarylation of arenes and heteroarenes using various styrenes in conjunction with a heterogeneous catalyst has been developed. Additionally, this method has been successfully extended to the hydroalkylation of styrenes by employing 1,3-dicarbonyl compounds as the nucleophile. Multigram quantities of diarylmethanes have been prepared using this new flow method

A highly efficient secondary benzylation procedure has been demonstrated using a high-valent heterobimetallic complex [Ir2(COD)2(SnCl3)2(Cl)2(μ-Cl)2] 1 as the catalyst in 1,2-dichloroethane to afford the corresponding benzylated products in moderate to excellent yields. The reaction was performed not only with carbon nucleophiles (arenes and heteroarenes) but also with oxygen (alcohol), nitrogen (amide
