酮的施密特重排的范围已扩展到酰基膦酸二烷基酯 (11a-111)。令人惊讶的是,发现 11a-11d 和 11g,其中酰基部分是单独的苯甲酰基或带有吸电子或轻度放电子取代基的苯甲酰基,产生了绝大多数由芳基的 C 到 N 迁移产生的产物组(N-芳基氨基甲酰基膦酸酯,12 和 N-芳基甲酰胺,15)。相反,带有强大的电子释放对烷氧基的芳烃羰基膦酸酯产生由膦酸酯基团从 C 迁移到 N 或消除的产物(N-芳烃羰基磷酰胺二烷基酯,13 和芳烃甲腈,分别为 17)

Acylphosphonates are conveniently synthesized from aryl iodides by a palladium‐catalyzed reaction with dialkyl phosphites under an atmosphericpressure of carbonmonoxide. The reaction demonstrates the first example of the use of phosphorus nucleophiles in related metal‐catalyzed carbonylation reactions.
