Studies on Synthesis and Properties of Some New Dibenzocyclobromonium Salts

Abstract

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).
