Nickel complexes unsaturated compound addition reactions

C=C double bond of aP-unsaturated steroidal esters. Several reports of addition reactions catalysed by transition metal compounds have also appeared. Diphenyl-phosphine adds to alkyl vinyl ethers with a high regioselectivity, in the presence of nickel(ii) and palladium(ii) complexes, giving the Markownikolf adducts (99). ... [Pg.21]

Most remarkably, no codimerization involving the unsaturated ester molecule is observed, even though nickel compounds such as the acrylonitrile complex are efficient catalysts for such codimerization reactions vide infra). An additional homodimer, l,3-bis(methylene)cy-clohexane (6), is formed as a minor product with phosphane-modified nickel catalysts. Only trace amounts of product 6 are obtained with maleic anhydride as cocatalyst. [Pg.2225]
