Abstract
Some new 3,7-disubstituted dibenzocyclobromonium salts were synthesized fro m 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' -disubst ituted biphenyls(or 2-bromo-4. 4' -disubstituted diphenylmethane) and 2-azi de-2'-bromo-4,4'-disubstituted biphenyls(20a-20d) respectively. Thermal rea ction of compounds 20a-20d gave corresponding polysubstituted carbozoles(21 a-20d).
