用茂钛配合物高效、高选择性催化4-乙烯基环己烯的异构化

摘要：

@@ The catalytic species [Cp2TiH], formed in situ from the reaction of titanocene dichloride with Grignard reagents having a β-H, was found to be a very effective catalytic system for isomerization of diolefin[1～3]. Based on our previous work[3], the titanium-catalyzed isomerization of 4-vinyl-cyclohexene (VCH) was studied in some detail. In this communication, we report the use of various substituted titanocene and polymer-supported titanocene complexes with Grignard reagents as catalyst for the isomerization of VCH. It was reported that base-catalyzed isomerization of VCH formed a very complicated mixture with 60 % conversion[4].
