Abstract

A novel InCl₃/SiO₂-catalyzed hydroarylation of various styrenes with arenes can be carried out under solvent-free conditions to afford a series of 1,1-di­arylalkanes in high yields and with good regioselectivities. The catalyst can be reused six times without obvious loss of catalytic activity.
