isolated as the ester, was obtained by the photostimulatedreaction of 2-chlorobenzoate ion with Ph2P – ions in good yield in liquid ammonia. The reaction did not occur in the dark; it was inhibited by m-dinitrobenzene and partially inhibited by a radical trap such as TEMPO. The results were consistent with the SRN1 mechanism. No evidences for aromatic nucleophilic substitution (SNAr) or benzyne mechanisms
2-(二苯基膦基)苯甲酸作为酯分离,通过 2-氯苯甲酸离子与 Ph2P - 离子在液氨中的光刺激反应获得。在黑暗中不发生反应;它被间二硝基苯抑制,部分被 TEMPO 等自由基陷阱抑制。结果与SRN1机制一致。没有发现芳香亲核取代 (SNAr) 或苄机制的证据。
