Abstract

Abstract:

Naphthyl-acrylophenones 1 are found to react with Q-phenylenediamine (bath temperature) yielding 2-(naphthyl) benzimidazoles 2 via cleavage of the ethylenic C=C bond. 2b and d are found to react with the diamine inn butanol giving the hitherto unknown benzo- 1,5-diazepmes 4. Electronic, i.r. and 1Hnmr spectra of the latter products as well as the reaction mechanism leading to the formation of the products 2 are discussed.

Keywords:

Benzimidazoles; O-Phenylenediamine
