摘要： 以4,4'-二取代联苯(或4,4'-二取代二苯甲烷)为原料合成了几种新的3,7-二取代二苯并环状溴(鎓)盐.对几种溴(鎓)盐与KBH4及与NaN3的反应进行了研究.结果表明,前一反应主产物为2-溴-4,4'-二取代联苯(或2-溴-4,4'-二取代二苯甲烷),后一反应的主产物为2-叠氮基-2'-溴-4,4'-二取代联苯(20a-20d).通过20a-20d的热反应合成几种新的多取代咔唑(21a-21d).

Abstract: Some new 3,7-disubstituted dibenzocyclobromonium salts were synthesized from 4,4'-disubstituted biphenyls(or 4,4'-disubstituted diphenylmethane). The reactions of some 3,7-disubstituted dibenzocyclobromonium salts with both KBH4 and NaN3 were studied. The primary products were 2-bromo-4,4'-disubstituted biphenyls(or 2-bromo-4,4'-disubstituted diphenylmethane) and 2-azide-2'-bromo-4,4'-disubstituted biphenyls(20a—20d) respectively. Thermal reaction of compounds 20a—20d gave corresponding polysubstituted carbozoles(21a—20d).
