The cyclotrimerization of alkyne (III) leads to a mixture of two isomers with a modest regioselectivity (86:14), whilst similar reactions of unsymmetrical alkynes (I) and (VIII) proceed with high regioselectivity (from 97:3 to

A nickel-based catalytic system has been developed for [2 + 2 + 2] cyclotrimerization of various alkynes, especially ynoates. This catalytic system enables facile construction of substituted aromatic compounds in excellent yields with high regioselec
