Selective catalytic oligomerizations and hydrogenations using polymer-anchored complexes of nickel and iridium

Abstract

Polystyrene–divinylbenene resin-anchored [Ni(CO)₂(PPh₃)₂] has been used selectively to oligomerize butadiene to either 4-vinylcyclohexene or cycloocta-1,5-diene, and anchored [Ir(Cl)(CO)(PPh₃)₂] selectively catalyses the hydrogenation of cyclo-octa-1,5-diene to cyclo-octene; the activity of these catalysts in some cases surpasses that of their homogeneous counterparts under identical conditions.
