coupling and intramolecular amidation of 2-carboxybenzaldehyde and amines. This one-pot synthesis gives excellent yields using ultrathin Pt nanowires as catalysts under 1 bar of hydrogen. These unsupported catalysts can also be used for the synthesis of phthalazinones in high yield when hydrazine or phenyl hydrazine is used instead of amines.
通过还原性C–N偶联以及2-羧基苯甲醛和胺的分子内酰胺化,已成功合成了一系列N取代的异吲哚啉酮。使用超薄Pt纳米线作为催化剂,在1 bar的氢气压力下,这种一锅法合成方法的收率很高。当使用肼或苯基肼代替胺时,这些未负载的催化剂也可用于高产率地合成邻苯二氮酮。
