摘要：
A new ruthenium complex, Ru(bpbp)(pbb) Cl, based on 2,6-bis(1-(phenyl)-1H-benzo[d] imidazol-2-yl) pyridine (bpbp) and 2-(1phenyl- 1H-benzo[d] imidazol-2-yl) benzoate (pbb) was synthesized. The complex Ru(bpbp)(pbb) Cl could catalytically oxidize 1(1H-benzo[d] imidazol-2-yl) ethanol to 1-(1H-benzo[d] imidazol-2-yl) ethanone with H2O2 as oxidant. Influence of temperature and catalyst amount on the oxidation reaction was evaluated. The reaction optimal conditions are as follows: molar ratio of catalyst to substrate to H2O2 is 1 : 1000 : 3000, the proper reaction temperature is 50 degrees C and reaction time lasts 5 h, and the isolated yield of 1-(1H-benzo[d] imidazol-2-yl) ethanol to 1-(1H-benzo[d] imidazol-2-yl) ethanone under the optimal reaction conditions is 57%.
