N-Benzylation of phenanthro[9, 10-d]triazole gave the mixture of 1-benzyl-1H- and 2-benzyl-2H-phenanthro[9, 10-d]triazole (1c and 2c) such as N-Alkylation. The mass specctrometry can be used to distinguish clearly between the 1-alkyl-1H- and 2-alkyl-2Hphenanthro-[9, 10-d]-triazole. The 1-alkyl compound releases more N2H, which is further split with the (R-H) elimination to give base peak m/z 190, than do the 2-isomer, and so on the mass spectrun of 2-alkyl compound a base peak is parent peak. However the fragmenta tion patterns of the two benzyl compounds show similarities so structures are proposed for these fragment ions by consideration of rearrangement fragment C14H8N+(m/z 190) and C6H5CH2+ (m/z 91).
