A number of 1 -aryl 1.2.3-triazoles have been synthesised; their U.V. absorption data and the apparent dissociation constants of the derived carboxylic acids are given. 1 -Aryl 1,2,3-triazoIes are nitrated and brominated in the 4-position of the phenyl ring.
A number of phenyl-, and p-bromophenyl-glyoxal bisarylhydrazones were prepared. Their acetylation, benzoylation, and cyclisation to 2,4-diaryl-1,2,3-triazoles were investigated. The U.V. and i.r. absorption data of the compounds prepared are given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
