Abstract
A process for the preparation of a compound of formula (V): comprising at least the step of reacting a compound of formula (VI) with a compound (VII) wherein; R2 is hydrogen or a C1-C20 hydrocarbyl radical provided that at least one R2 is not hydrogen; R5 is hydrogen or a C1-20 hydrocarbyl group optionally containing one or more heteroatoms from groups 14-16; R6 is hydrogen or a C1-20 hydrocarbyl group optionally containing one or more heteroatoms from groups 14-16; n is 1, 2 or 3; each R8 is a C1-20 hydrocarbyl group; and Hal is a halide; in the presence of a nickel imidazolidin-2-ylidene compound.
