palladium-catalyzed synthesis of arylphosphonates from arenediazonium tetrafluoroborates and triethylphosphite or diethylphosphite is presented. The reaction tolerates useful substituents including bromo, chloro, nitro, ether, cyano, keto, and ester groups, can be performed as a one-pot process from anilines omitting the isolation of arenediazonium salts, and can be extended to the preparation of arylphosphine
新颖的钯催化四氟硼酸芳氮唑鎓和四氟硼烷鎓的芳基膦酸酯的合成 亚磷酸三乙酯或亚磷酸二乙酯。该反应可耐受有用的取代基,包括溴,氯,硝基,醚,氰基,酮基和酯基,可通过一锅法从苯胺制得,而无需分离芳族重氮盐,并可扩展至芳基膦氧化物的制备和芳基膦。
