摘要：

The reaction of [(CO)(PPh3)2Re(mu-NCHPh)Ru(PPh3)2(PhCN)] (2) with HBF4-Me2O generates [(CO)(PPh3)2Re(mu-H)2(mu-eta1,eta2HNCHPh)Ru(PPh3)2(PhCN)][BF4] (3). Monitoring the reaction by NMR spectroscopy shows the intermediate formation of [(CO)(PPh3)2HRe(mu-H)2(mu-NCHPh)Ru(PPh3)2(PhCN)][BF4] (4). Attempted reduction of the imine ligand by a nucleophile (H- or CN-) failed, regenerating 2. Under dihydrogen at 50 atm, 3 is slowly transformed into [(CO)(PPh3)2HRe(mu-H)3Ru(PPh3)2(PhCN)][BF4] (5) with liberation of benzyl amine.
