Abstract

Abstract: A bifunctional nickel initiator, bis (~-trifluoroacetato)(~~:~~-2, 2'-biallyl) dinickel (II), IV, was synthesized to promote the living polymerization of butadiene to high cis-1, Ccontent polymer with both chain ends active. Other potential initiators,[1, 4-phenylenebis ((73-1-allyl) nickel trifluoroacetate)],, 11, and [1, 4-~ yclohexanediylbis ((73-1-allyl)-nickel trifluoroacetate)]", III, were found to be completely ineffective due to intermolecular ...
