The cross-dimerization of diphenylacetylene with trimethylsilylacetylene via C-H bond cleavage in the presence of a catalytic amount of bis(cyclooctadiene)nickel [Ni(cod)2] together with a pyridine-based ligand efficiently proceeds to give the corresponding enyne compound with good yield. In contrast, their 1:2 cross-trimerization leading to a dienyne derivative takes place selectively using a triarylphosphine ligand. The regioselective cross-dimerization of some unsymmetrical internal arylalkynes with terminal silylacetylenes is also accomplished using the pyridine ligand.
