Patent

CA 2043798

The title compounds can be prepared by reaction of a styrene derivative with ethylene in the presence of a nickel catalyst which carries a phosphorus-oxygen chelate ligand, at a temperature of 20 to 160°C and an ethylene pressure of 1 to 200 bar. Styrene derivatives extended with ethylene, of the formula Image in which R19 denotes hydrogen, C1-C4,-alkyl, vinyl or chlorine and R38 denotes C1-C4-alkyl, C2-C4-alkenyl, C2-C7-acyl, fluorine, chlorine or bromine and m assumes values of 4-104, with the exception of compounds wherein R19 denotes hydrogen and R38 denotes i-butyl or benzoyl, and m assumes the value 4, are new.
