Abstract

(Chemical Equation Presented) The reaction of the internal alkynyl ketones 1 (n = 1) under the combined catalyst, AuCl₃ and AgSbF₆, gave the enones 2 in good to high yields, whereas that of the terminal alkynyl ketones 1 (n = 0) under the combined catalyst, AuCl₃ and AgOTf, afforded the cyclic enones 3.
