Abstract:
The present disclosure relates to a method for preparing various physiologically active pharmaceutical ingredients, such as a 1,1-diaryl compound and a 1,1-diheteroaryl compound (specifically, a 1,1-diaryl carbonyl compound), in an economical and convenient manner under mild conditions without using an expensive transition metal catalyst by activating an alkyne compound (e.g., an ynamide) using a Brønsted acid as a catalyst to induce a reaction of the activated alkyne compound and a N—O bond oxidant to form an adduct intermediate and then inducing a coupling reaction of the adduct intermediate with various nucleophilic organic compounds (e.g., a nucleophilic arene compound).

Claim (Index 10):
The method of  claim 9 , wherein the Br\u00f8nsted acid is selected, according to the structure of a counter anion, from the group consisting of (i) conjugate acids of sulfonate, bis-sulfonimide, phosphate, phosphoramide, or carboxylate, for oxygen acids and nitrogen acids; (ii) conjugate acids of carbanions with aryl groups attached thereto, the aryl groups comprising one to three CF 3 , C 6 F 5 , SO 2 CF 3 , SO 2 C 6 F 5  groups and three to five F atoms, for carbonic acids;, and (iii) a combination thereof.
