钯催化的烯烃的芳酰化反应是通过使用酰基铬酸酯作为酰基供体进行的。当用芳基碘、酰基铬酸盐和催化量的Pd（OAc）2/2 P（o-Tol）3处理活性烯烃如异戊烯和甲氧基丙二烯时，这些烯烃的芳基酰化在室温下进行。从具有分子内烯烃部分的芳基碘，环化-酰化产物通过分子内芳基钯化，然后与酰基铬酸酯酰化而获得。
Palladium-catalyzed arylacylation of alkenes proceeds by employing acylchromates as acyl donors. When active alkenes such as norbornene and methoxyallene are treated with an aryl iodide, an acylchromate, and a catalytic amount of Pd(OAc)2/2P(o-Tol)3, arylacylation of these alkenes proceeds at room temperature. From aryl iodides having an intramolecular alkene moiety, cyclization–acylation products are obtained via intramolecular arylpalladation followed by acylation with acylchromates.
