Quasi-nature catalysis: developing C-C bond formations catalyzed by late transition metals in air and water.

This Account outlines the recent efforts of developing catalysis under the ambient conditions of air and water for synthetic purposes from the author's laboratory. The discussions are focused on catalytic reactions (mostly C-C bond formations) other than oxidations via late transition metals. It includes the following aspects: (1) copper-catalyzed C-C bond formations; (2) palladium-catalyzed C-C bond formations; (3) rhodium-catalyzed C-C bond formations; (4) ruthenium-catalyzed olefin isomerizations and C-H activations. The mechanism, limitations, and synthetic applications of these reactions are also discussed.
