closely-spaced bromomethyl groups under conditions of phase-transfer catalysis occur as cycloalkylation to form new types of fused systems, in which aromatic rings are annelated with a five-, six-, or seven-membered ring containing the exocyclic phosphorus containing and cyano substituents. The reaction pathway is independent of the reagent ratio. Under the same conditions, the reaction with 1,3,5-tris(bromomethyl)-2
在相转移催化条件下,磷酰基和硫代磷酰基乙腈与含有紧密间隔的溴甲基的聚(溴甲基)芳烃的反应以环烷基化的形式发生,形成新型稠合系统,其中芳环与五、六- ,或含有环外含磷和氰基取代基的七元环。反应途径与试剂比例无关。在相同条件下,与 1,3,5-三(溴甲基)-2,4,6-的反应三甲苯在起始底物的所有亲电子基团上提供单烷基化产物。在所得化合物中,磷原子上的烷氧基很容易通过相应的甲硅烷基醚转化为羟基,得到相应的磷酸,而氰基是化学惰性的。
