Abstract

In this contribution, we study the conversion of a bio-sourced unsaturated fatty ester by cross-metathesis with nitrile-functionalized olefinic partners (acrylonitrile and crotonitrile). A switch from terminal to internal olefins leads to higher conversion. This is in part rationalized by involvement of a more stable ruthenium ethylidene species with crotonitrile. A new carbenic complex forms upon reaction with the nitrile-functionalized olefins, that is also catalytically active. [ABSTRACT FROM AUTHOR]
