Polyfunctional imidazoles: XIV. 4-sulfonyl-5-formyl-1H-imidazoles

Autor: A. N. Grozav, M. V. Vovk, V. I. Dorokhov, V. A. Chornous

Publikováno v: Russian Journal of Organic Chemistry. 53:1548-1555

Oxidative chlorination of 1-aryl-4-benzylsulfanyl-1H-imidazole-5-carbaldehydes gave 1-aryl-5-formyl-1H-imidazole-4-sulfonyl chlorides which reacted with secondary amines and phenols to produce the corresponding N,N-disubstituted 5-formylimidazole-4-s

Synthesis, thermal stability and mass spectra of 2-trihalomethyl-1,3,5-dithiazin-4-ones and their 2,3-dihydro derivatives

Autor: M. V. Vovk, V. I. Dorokhov, I. G. Krainikova

Publikováno v: Chemistry of Heterocyclic Compounds. 31:868-872

A method has been proposed for the synthesis of 2-trihalomethyl-1, 3,5-dithiazines based on the reaction of 1 1, -dithiols with 1, 1-dichloro- and I -chloroalkyl isocyanates. The thermal stability and mass spectra of these compounds were studied.
