Platinum-catalyzed cross-dehydrogenative coupling reaction in the absence of oxidant

A third strategy for cross-dehydrogenative coupling reaction has been reported via platinum-catalyzed sp(3) C-H and sp(3) C-H coupling reaction in the absence of oxidant. Nitroalkanes as well as dialkyl malonate derivatives, beta-keto esters and malononitrile are active participants in this coupling reaction. Both cyclic and acyclic non-activated simple ketones are good reactants in this reaction.
