主 题:1 5-Diarylpyrazole HY-zeolite Baylis-Hillman Heterogeneous catalysis
摘 要:A facile and convenient protocol was developed for the synthesis of 1,5-diarylpyrazoles using Baylis-Hillman adducts in the presence of HY-zeolite as an efficient recyclable heterogeneous catalyst in reasonable reaction times(1.5-2.5 h) and high yields (78-90%).
