react with benzenethiol to give the phenylthio-compounds RnM(SPh)3–n. These reactions can be initiated by di-t-butyl hyponitrite, and sometimes inhibited by galvinoxyl or phenothiazine. It is concluded that the reactions take place by a homolytic chain mechanism, where the product-forming step involves bimolecular homolytic substitution by the phenylthioradical at the metal centre.
三有机锑和-铋化合物R 3 M(M = Sb或Bi,R = Me,Et或Ph)与苯硫醇反应生成苯硫化合物R n M(SPh)3- n。这些反应可以由亚硝酸二叔丁基酯引发,有时可以被加尔维诺尔或吩噻嗪抑制。结论是反应是通过均相链机理进行的,其中产物形成步骤涉及在金属中心被苯硫基自由基进行双分子均相取代。
