Abstract: Linear Mn(Ⅱ) coordination polymer is prepared from 4'-(4-pyridyl)-2,2':6',2″-terpyridine and MnCl2,and used to catalyze the oxidation of benzyl secondary alcohols by t-BuOOH.Results show that acetonitrile is the most suitable solvent in the catalytic system;Catalytic amount of base can significantly promote the reaction.This method can be used to oxidize different types of benzyl secondary alcohols with a wide range of substrates.After reaction has performed at 80℃ for 3-5 hours,excellent conversions (95%-99%) and high yields of 13 substrates with different structures are obtained.The catalyst still remains a high catalytic efficiency after 4 times of reuses.
