摘要：

Effects of various cation-exchanged faujasite zeolites with different Si/Al ratios are studied in the thia-Michael addition of benzenethiol to cycloalkenones. The observed catalysis is rationalized by a mechanism involving simultaneous participation of acidic/basic sites of zeolites, which is supported by IR data on enone/zeolite composite.
