N-alkylation of phenanthro[9,10-d]triazole

N-Alkylation of phenanthro [9, 10-d] triazole [1a] gave the mixture of 1- and 2-alkyl derivatives, the latter being predominant. The ratio of these isomers was in contrast to the N-methylation of benzotriazole [3a]. N-Phenylation of [1a] gave the 2-phenyl derivativ e [2f] exclusively. The 2-position...

Summary:N-Alkylation of phenanthro [9, 10-d] triazole [1a] gave the mixture of 1- and 2-alkyl derivatives, the latter being predominant. The ratio of these isomers was in contrast to the N-methylation of benzotriazole [3a]. N-Phenylation of [1a] gave the 2-phenyl derivativ e [2f] exclusively. The 2-position of [1a] was alkylated in preference to the 1-position, contrary to the previous paper.
