Abstract

Quaternary salts of pyridine and related compounds are a topic of numerous reports. In the present review, eight chapters are devoted to selected examples of these compounds describing their syntheses, physicochemical properties and possible applications, along with their biological activities. The ninth chapter deals with the chemistry of viologens, while the tenth reviews selected work from our research group on benzonaphthyridinium quaternary salts.

Keywords: quaternary salts, pyridines, benzonaphthyridinium quaternary, quaternary azaaromatics
