Alkynes nickel tetracarbonyl catalyst

Indirect evidence has been obtained in support of the proposed mechanism for the formation of ten-membered rings from the reactions of butadiene and alkynes in the presence of zerovalent nickel catalysts. ao)-Octadienediyltriphenylphosphinonickel(o) reacted with dimethyl acetylenedicarboxylate to give a red solution from which the yellow crystalline complex (35) could be isolated. This complex (35) absorbed four equivalents of carbon monoxide to give nickel tetracarbonyl and the cyclodeca-triene (36) ... [Pg.285]
