Directing Effect

The study of the regioselectivity of insertion of unsymmetrical alkynes into the carbon–carbon bond of oxetan-3-one in the presence of a nickel catalyst has revealed a strong directing effect of a 2-thienyl substituent. This effect is larger than those of 2-vinylbenzene, trimethylsilyl, aryl, or 3-thienyl groups.
