✦ Synopsis
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.
