TETRAZOLES. XIV. PRODUCTION OF N-BENZOYLTETRAZOLES AND THEIR CHEMICAL CHARACTERISTICS

Myznikov, Yu. E.,Koldobskii, G. I.,Vasil'eva, I. N.,Ostrovskii, V. A.

, p. 1397 - 1401 (2007/10/02)

The acylation of 5-phenyltetrazole by substituted benzoyl chlorides in the methylene chloride-water two-phase system in the presence of tetrabutylammonium bromide leads to the formation of the isomeric 1-benzoyl- and 2-benzoyl-5-phenyltetrazoles.N-Benzoyltetrazoles have high reactivity and can be recommended as effective reagents for the acylation of compounds containing a mobile hydrogen atom.
