Abstract
9-Benzylfluorene( 2) was synthesized by two different methods. One method is that fluorene( 1) reacts with n-BuLi to give red mixture solution,and then the mixture solution reacts with benzylchloride to obtain target product( 2).Another method is that fluorene( 1) reacts with sodium benzyloxide solution in a bomb to yield target product( 2). The former way needs low temperature and anhydrous anaerobic operation. The latter way is better than the anterior way because material is cheaper and yield is higher. The products were characterized by elemental analysis and NMR spectroscopy.
