Complexes (dad) 2 RuCl 2 ( 1 ) (dad = diazadiene, RN = CR'– CR'=NR) are reduced to (dad) 2 Ru ( 2 ) which react with L = CO or ethylene to give (dad) 2 RuL ( 3,5 ). Reduction of 1b ( R' = H) with magnesium–butadiene or reaction of 2b with butadiene leads to a new type of C–C coupling of butadiene to one of the diazadiene ligands ( 6b ). Addition of CO induces a rearrangement to 7b by a hydride shift.
