Bisphosphinoaryl ruthenium(II) compounds are synthesized using two distinct synthetic routes. One route, direct cycloruthenation, consists of the reaction of the parent arene compound R-PCHP with [RuCl 2(PPh 3) 3] in chlorinated solvents. However, this route suffers from major drawbacks because HCl is formed as well as free triphenylphoshine. The other route, the transcyclometalation reaction, involves the interconversion of one cyclometalated ligand metal complex, [RuCl(NCN)(PPh 3)], into another complex, [RuCl(R-PCP)(PPh 3)], with concomitant consumption and formation of the corresponding arenes R-PCHP and NCHN, respectively.
