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
[reaction: see text] 1,1-Diarylalkanes are easily synthesized by CH-functionalization reactions of electron-rich arenes and heteroarenes with styrenes in the presence of FeCl(3) as catalyst.

Iodine mediates the hydroarylation of styrenes with arenes and heteroarenes to afford 1,1-diarylalkanes in good to high yields. Details regarding the substrate scope and selectivity of this hydroarylation reaction are discussed.

heteroarenes with unactivated alkenes by Au(III)-catalyzedintermolecularhydroarylationunder mild reaction conditions was developed. This method features a short reaction time (5 h) under mild conditions and has a broad substrate scope, including electron-rich arenes and heteroarenes, terminal and internal substituted aryl alkenes, and unactivated aliphatic alkenes.

A novel InCl 3 /SiO 2 -catalyzed hydroarylation of various styrenes with arenes has been developed. The reaction can be carried out under solvent-free conditions to afford a series of 1,1-di-arylalkanes in high yields and with good regioselectivities. The catalyst can be reused six times without obvious loss of catalytic activity.
