Abstract

The reaction of [(CO)(PPh3)2Re(mu-NCHPh)Ru(PPh3)2(PhCN)] (2) with HBF4 -Me2O generates Re(mu-H)2(mu-eta1,eta2HNCHPh)Ru(PPh3)2(PhCN)][BF4] (3) . Monitoring the reaction by NMR spectroscopy shows the intermediate f ormation of O)(PPh3)2HRe(mu-H)2(mu-NCHPh)Ru(PPh3)2(PhCN)][BF4] (4). At tempted reduction of the imine ligand by a nucleophile (H- or CN-) fai led, regenerating 2. Under dihydrogen at 50 atm, 3 is slowly transform ed into [(CO)(PPh3)2HRe(mu-H)3Ru(PPh3)2(PhCN)][BF4] (5) with liberatio n of benzyl amine.
