Treatment of trans- (dppe = Ph2PCH2CH2PPh2) with N,N-dimethylformamide (DMF) in benzene under reflux afforded trans-, together with a hydridocarbamoyl complex 2-CONMe2)(dppe)2> as the intermediate stage of this decarbonylation reaction.The detailed structure of the latter complex was determined by X-ray crystallography.Reaction of trans- with N2 afforded trans-, whose solution in benzene was further converted into a coordinatively unsaturated complex under reflux in an Ar atmosphere.Subsequent treatment of with H2 gas gave a dihydrido complex .
