چکیده
|
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-(1-phenyl-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°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%. © 2017 shenggui liu et al.
