Synthesis and nucleophilic reactions of N-(1-Naphthyl)-3,4-methylenedioxybenzyl-idinehomophthalisoimidium perchlorate

Azab,Madkour,Mahmoud

, p. 393 - 402 (2002)

N-(1-Naphthyl)-3,4-methylenedioxybenzylidinehomophthalisoimidium perchlorate 6 was obtained via treatment of N-(1-naphthyl)-3,4-methylenedioxybenzylidine homophthalamic acid 5 with perchloric acid in acetic anhydride. The behaviour of 6 towards active methylene-containing compounds, Grignard reagents and aromatic primary amines and hydrocarbons, has been investigated.
