An important step forward in the search for catalytically active polynuclear metal complexes has been made by George G. Stanley's group: The bimetallic complex cations r~c-[Rh,(nbd),L]~+ l r and rne~o-[Rh,(nbd),L]~+ l m (nbd = norbornadiene) which were isolated as tetrafluoroborates (Scheme l),[l1 w
T = 25 "C, t = 3.5 h) also showed that complex 1 is able to perform more than 36 000 (yield 99.9 YO) without loss of activity. In order to rule out the participation in the catalysis of free, solvated [Rh(PPh,),]+ or similar cationic species formed by dissociation of complex 1, two independent expe
