Abstract:
A process which comprises:(a) reacting an amine-functionalized support of the structure: Q--NH.sub.2 wherein Q is an inorganic solid or polymer support, with a compound of the formula X--A--L, wherein X is a leaving group, A is a linking group, and L is a polymerization-stable pi-bonded ancillary ligand that is covalently bonded to A, to produce a supported ligand of the formula: Q--NH--A--L; and(b) reacting the supported ligand with a transition or lanthanide metal compound to produce a tethered catalyst of the structure: ##STR2## where M is a Group 3 to 10 transition or lanthanide metal, Y is a ligand selected from the group consisting of halide, alkoxy, siloxy, dialkylamino, C.sub.1 -C.sub.10 alkyl, C.sub.6 -C.sub.15 aryl, C.sub.7 -C.sub.15 alkaryl or aralkyl, and n is the number of Y groups and equals the valence of M minus 2.
