茂型铼羰基配合物催化Friedel-Crafts酰基化反应研究

Study on the Catalytic Reactivity of Metallocene Rhenium Carbonyl Complexes in Friedel-Crafts Acylation

研究了3种茂型双核铼羰基配合物催化苯甲醚及其衍生物与多种酰化剂的Friedel-Crafts酰基化反应.结果表明:配合物在催化Friedel-Crafts酰基化反应中均显示出了一定程度的催化活性,催化效果受到苯环上取代基的电子效应、空间效应和不同酰化剂结构的影响.

This paper researched the Friedel-Crafts acylation reactions of aromatic compounds with a variety of acylation reagents catalyzed by three metallocene rhenium carbonyl complexes.The results indicated that these rhenium carbonyl complexes had certain degree catalytic activity in Friedel-Crafts acylation reaction.The catalytic effect was influenced by the electronic and steric effects of the substituents on the benzene ring,and the structures of different acylation reagents.
