Oxidation of Olefins Using Rhenium Supported by Imidazole-Functionalized Amphiphilic Copolymers

Abstract

Well-defined amphiphilic EO 45 -b-MA m block copolymers modified with aminopropyl-imidazole groups are used as a support for methyltrioxorhenium. This material appears to be a good catalyst for the oxidation of olefins into the corresponding diols and can be recycle-used.

Methyltrioxorhenium-catalysed oxidation of pseudocumene in the presence of amphiphiles for the synthesis of vitamin E

“…[30][31][32][33] Furthermore, the use of an imidazole-functionalised amphiphilic copolymer linked to MTO has been recently reported as a recyclable catalyst for epoxidation, setting a precedent in its field. 34 Hence, given the high importance of benzoquinone 3 as an intermediate in the synthesis of vitamin E, we report herein the MTO-catalysed selective oxidation of pseudocumene in the presence of different amphiphiles as an appealing alternative to the existing methods and to improve product selectivity of 3.…”
