N-（2 ′-苯基苯基）苯磺酰胺与丙烯酸酯在Pd（OAc）（2）、Cu（OAc）（2）和碱的催化体系存在下，在空气中通过2 ′-位C-H键的断裂反应，高产率地生成5，6-二氢-5-（苯磺酰基）菲啶-6-乙酸酯衍生物。苯甲酸与丙烯酸丁酯和苯乙烯反应也可分别得到3-[（丁氧羰基）甲基]苯酞和3-苯基异香豆素。
N-(2'-Phenylphenyl)benzenesulfonamides react with acrylate esters accompanied via cleavage of the C-H bond at their 2'-position in the presence of a catalyst system of Pd(OAc)(2) and Cu(OAc)(2) and a base under air to produce 5,6-dihydro-5-(benzenesulfonyl)phenanthridine-6-acetate derivatives in high yields. The reactions of benzoic acid with butyl acrylate and styrene can also give 3-[(butoxycarbonyl)methyl]phthalide and 3-phenylisocoumarin, respectively.
