Abstract The reaction of p-substituted benzyl bromides with the >P—O− ions in THF, alcohols and toluene as the solvents is described. According to the reduction potential of the p-substituted benzyl bromides and the solvent used the formation of the P—C bond, debromination and/or dimerization occur. The principal process is believed to be X-philic substitution, the dimers are formed through a secondary
摘要 描述了对取代苄基溴与 >PO- 离子在四氢呋喃、醇和甲苯作为溶剂中的反应。根据对位取代苄基溴化物的还原电位和所用溶剂形成PC键,发生脱溴和/或二聚反应。主要过程被认为是亲 X 取代,二聚体通过二次过程通过 SET 从对位取代的苄基阴离子形成对位取代的苄基溴。
