title: Ni-catalyzed ketene cycloaddition: a system that resists the formation of decarbonylation side products.
abstract: Ni-phosphine complexes were used as catalysts for the cycloaddition of various ketenes and diynes. In general, 2,4-cyclohexadienones were formed instead of products arising from decarbonylation of the ketenes.
