✦ Synopsis

Chelate ligands have an unusual controlling effect on nickel catalyzed oligomerization and polymerization of ethylene",']. In this communication arsenic-containing chelate ligands are presented for the first time as oligomerization-catalysts.

Reaction of benzoylmethylenetriphenyl-h5-arsane 1 with bis( 1,5-cyclooctadiene)nickel [ N i ( ~o d ) ~] in toluene yields an in-situ catalyst which oligomerizes ethylene un-
