Polymer-supported transition metal complexes and use thereof in catalysis of olefin metathesis.

Abstract

Supports for transition metal complexes with decreased bleeding out in supercrit. CO2 solvents for the title reaction are based on polyethoxylated 4-hydroxyethylstyrene polymers or N-substituted acrylamide-styrene copolymer-silica gel adducts. A typical support was manufd. by reaction of trans-3-(4-isopropoxy-3-vinylphenyl)acrylic acid with Hypogel 400 [divinylbenzene-amine-terminated ethoxylated 4-hydroxyethylstyrene (ethoxylation degree 10) copolymer].
