A facile catalyticenantioselective 1,2‐addition of diynes to trifluoromethyl ketones was developed. By a combination of Me2Zn, Ti(OPr‐i)4, BaF2 and quinine, the reaction of a series of terminal diynes with trifluoromethyl ketones proceeded to afford trifluoromethylated chrial tertiary alcohols with the diyne moiety in good to high yields with moderate to high enantioselectivities. Furthermore, this
