英文摘要	some heterogeneous catalysts, cupric oxide supported on different supports, were prepared and employed to catalyze the cyclopropanation of styrene and 2,5-dimethyl-2,4-hexadiene with ethyl diazoacetate (eda). the catalytic performance for cyclopropanation strongly depends on the nature of the support. a novel catalyst, cuo/tio2-al2o3, in which al2o3 is modified with a monolayer tio2, is found to be most active and selective for the cyclopropanation reaction. the yields of 93 and 94% cyclopropanes are obtained for styrene and 2,5-dimethyl-2,4-hexadiene at 40 degreesc as the substrates, respectively. the activity and selectivity in cyclopropanes are optimized with a monolayer dispersion of cupric oxide on the corresponding supports.
