Iridium- and rhodium-catalyzed C–H activation and formyl arylation of benzaldehydes under chelation-assistance†
Abstract
Mild and efficient synthesis of benzophenones via Ir(III)- and Rh(III)-catalyzed, directing group-assisted formyl C–H arylation of benzaldehydes has been achieved using diaryliodonium salts, in which Rh(III) and Ir(III) catalysts exhibited a complementary substrate scope.
