trifluoromethanesulfonate as catalysts in the presence of triphenylphosphine. This synthesis process involves nitrene formation, C–H bond insertion, C═C bond rearrangement, and C–N bond formation cascade reactions via copper- and molybdenum-catalyzed mediation. The method features a wide substrate scope and a moderate to high yield (up to 90%), exhibiting the possibility for practical applications
提出了一种在三苯基膦存在下,以乙酰丙酮钼和三氟甲磺酸铜 (II) 为催化剂,从邻硝基苯甲酸N-烯丙基酰胺合成 1,4-苯二氮卓-5-酮的新型有效方法。该合成过程包括氮烯形成、C-H 键插入、C=C 键重排以及通过铜和钼催化介导的 C-N 键形成级联反应。该方法具有广泛的底物范围和中高产率(高达 90%),具有实际应用的可能性。
