VERFAHREN ZUR HERSTELLUNG VON AN DER DOPPELBINDUNG MIT ETHYLEN VERLAENGERTEN STYROL-DERIVATEN MIT IN DER GEBILDETEN VERLAENGERUNGSKETTE VERBLEIBENDER DOPPELBINDUNG |
摘要 |
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 formulain whichR19 denotes hydrogen, C1-C4-alkyl, vinyl or chlorine andR38 denotes C1-C4-alkyl, C2-C4-alkenyl, C2-C7-acyl, flourine, chlorine or bromine andm 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. |
