Regioselectivity in interaction of bifunctional o‐quinone annulated with dithiete cycle with tris(dibenzylideneacetone)dipalladium (Pd 2 dba 3 ) in presence of bidentate phosphines was studied. Excluding the case of 1,2‐bis(diphenylphosphino)ethane (dppe) species, the formation of corresponding dithiolates with high yields was observed. Coordination of palladium to the dithiolene site of bifunctional ligand causes a distortion of the dioxolene site as well as significant decrease of its electron‐acceptor ability. The formation of both catecholate and dithiolate isomers, observed in case of reaction with dppe, might be interpreted as a consequence of kinetic factors.
