Nickel(O) Catalyzed Reactions Involving Strained σ Bonds
Although extensive studies have been done in organic chemistry with unsaturated carbon-carbon bonds, only little has been known about reactions in which a carbon-carbon single bond is involved. Certain strained a bonds are activated under the influence of transition metal complexes and undergo characteristic transformations. Examples illustrating the intriguing operations of nickel(O) complexes will hereinafter be described. One of the most important characteristics of the Ni(O) catalysts is that the complexes, unlike other metal complexes, can promote the intermolecular coupling reactions involving carbon-carbon σ bonds.
