Abstract

The application of n-C3H7Li and n-C4H9Li as cocatalysts for the homogeneous metathesis of 2-pentene with WCl6 was investigated. Disproportionation of alkyl radicals generated during the formation of the active catalyst complex results in the production of alkenes, which participate in the metathesis reactions and lead to a small amount of distinct by-products.

Abstract

Было исследовано применение H-C3H7Li и H-C4H9Li в качестве сокатализаторов прн гомогенном метатезисе 2-пентена с WCl6. Диспропорционировавание алкильных радикалов, генерируемых при образовании активного комплекса катализатора, приводит к алкенам, которые принимают участие в реакции метатезиса с выходом небольших количеств опеделенных побочных продуктов.
