ACTIVATION OF SUPPORTED OLEFIN METATHESIS CATALYSTS BY ORGANIC REDUCTANTS

摘要

An organic reductant, in particular an organosilicon reductant suitable for activating supported catalysts of the type MOnEm, wherein E is S and/or Se, in particular MOn, wherein M is W, Mo or Re, is described as well as its use in metathesis reactions. The reduced catalysts are able to metathesize olefins at low temperatures and are therefore also suitable for metathesis of functionalized olefins.
