Cationic diruthenium (II,III) tetracarboxylate catalysts have been shown to catalyze selective intermolecular C-H functionalization reactions using donor/acceptor carbenes in high yield and with levels of enantioselectivity. The were compared the analogous dirhodium (II,II) showed similar enantioselectivity for most reactions. A distinctive feature is a greater preference over cyclopropanation corresponding catalysts. Also, sterically more accessible sites their counterparts. These studies show that are generally effective enantioselective functionalization, but further optimization would be needed them match terms functional group compatibility, turnover frequency, numbers.
