Multi-component cascade transformations including difunctionalization of two alkynes with both syn- and anti-selectivity in one catalyst system is challenging. Herein, the authors report a Nickel-catalyzed four-component reaction to access densely substituted 1,3-dienes using two terminal alkynes, aryl boroxines, and perfluoroalkyl iodides.
