摘要

Thermal decomposition reactions of N-alkyl-2-aminobiphenyls were investigated by passing vapors of the aromatic amines over calcium oxide at 450 C–600 C. The procedure afforded a method for the preparation of carbazole (69%) and phenanthridine (92%)[1]. Hence, thermal decomposition reactions may also be utilized for the syntheses of other N-containing heterocycles which are of great importance in the field of medicine [2] and some areas in ...
