The first synthetic application of Ti(IV)–calix[4]arenes as catalysts in regio- and stereoselective epoxidation of allylic alcohols is reported. The catalytic properties of these Ti(IV) complexes are dramatically enhanced in the presence of activated 4 Å molecular sieves.
据报道,Ti(IV)–calix [4]
芳烃在烯丙基醇的区域和立体选择性环氧化中作为催化剂的首次合成应用。在活化的4Å
分子筛的存在下,这些Ti(IV)配合物的催化性能得到显着提高。
