An efficient carbonylative procedure for the synthesis of 3-arylquinoin-2(1H)-ones has been established. Through a palladium-catalyzed aminocarbonylation of benzyl chlorides with anthranils, a variety of 3-arylquinoin-2(1H)-one products were obtained in moderate to excellent yields with good functional group tolerance.

A palladium-catalyzed carbonylative cyclization of benzyl chlorides with o-nitrobenzaldehydes has been developed for the synthesis of 3-arylquinolin-2(1H)-ones. Mo(CO)6 played a dual role as both a CO surrogate and a reductant in this carbonylative transformation.

The invention discloses a preparation method of a 3-aryl quinoline-2 (1H) ketone derivative. The method comprises the following steps: carrying out a reaction on palladium acetate, S)-1, 1'-binaphthyl-2, 2'-diphenylphosphine, carbonyl molybdenum, triethylamine, water, benzisoxazole and a benzyl chloride compound at 100 DEG C for 26 hours, and after the reaction is completed, carrying out post-treatment to obtain the 3-aryl quinoline-2 (1H) ketone derivative. According to the preparation method, benzisoxazole is used as a nitrogen source and a formyl source, the operation is simple, the reaction initial raw materials are cheap and easy to obtain, the tolerance range of substrate functional groups is wide, and the reaction efficiency is high; and various 3-aryl quinoline-2 (1H) ketone derivatives can be synthesized according to actual needs, and the practicability of the method is widened while the operation is convenient.
