Organonickel cyanide chemistry. Reactions of [(PhC≡CPh)Ni(CN)2]2-. An improved synthesis of [Ni(CN)2(CO)2]2-

The reactions of (K·18-crown-6)2[(η2-PhC≡ CPh)Ni(CN)2] (1) with CO, P(OMe)3, alkynes, and α-bromo-p-xylene are described. Reaction of 1 with CO provides a route to a pure, stable salt of the Ni(CN)2(CO)22- anion. Compound 1 is a catalyst for the trimerization of terminal alkynes.
