Synopsis. Upon UV irradiation in methanol,diaryl triphenylmethylphosponate underwent three types of elimination of two aryl groups to give biaryls: the first is an α,α-elimination of two phenyl groups from a triphenylmethyl group which leads to formation of the corresponding carbene intermidiate; the second is an elimination of two aryl groups from a diaryl ester group to afford biaryl; the third is an elimination of phenyl and aryl groups from both moieties to give arylbenzene.
摘要。在
甲醇中紫外线照射下,二芳基三苯甲基
磷酸酯经历了三种类型的消除反应,去除两个芳基,形成了双
芳烃:第一种是从三苯甲基基团中α,α-消除两苯基,导致相应的卡宾中间体的形成;第二种是从二芳基酯基团中消除两个芳基,以生成双
芳烃;第三种是从两个部分消除苯基和芳基,生成芳基苯。
