Highly selective photo-catalytic dimerization of α-methylstyrene by a novel palladium complex with photosensitizing ruthenium(ii) polypyridyl moiety

A novel dinuclear complex containing the photo-sensitizing Ru unit and a Pd center is effective toward selective catalytic dimerization of alpha-methylstyrene leading to 2,4-diphenyl-4-methyl-1-pentene under visible-light irradiated conditions.
