N-Phenylamide and phenyl (thio)esters of 3-phenylpropiolic acid add benzene in the presence of CF3SO3H or AlX3 (X = Cl, Br) to give 4,4-diphenyl-3,4-dihydroquinolin-2-one, 4,4-diphenyl-3,4-dihydrocoumarin, and 4,4-diphenyl-3,4-dihydrothiocoumarin, respectively.
在 CF3SO3H 或 AlX3(X = Cl、Br)存在下,3-苯基丙炔酸的 N-苯酰胺和苯基(硫)酯加入苯,分别得到 4,4-二苯基-3,4-二氢喹啉-2-酮、4,4-二苯基-3,4-二氢香豆素和 4,4-二苯基-3,4-二氢硫代香豆素。
