BENZAZOLIN-2-THIONES IN THE MICHAEL REACTION. 1. REACTION OF BENZOTHIAZOLIN- AND BENZOXAZOLIN-2-THIONES WITH ACRYLONITRILE, ACRYLAMIDE, AND METHACRYLATE IN THE PRESENCE OF ACID CATALYST

The reaction of benzothiazolin- and benzoxazolin-2-thiones with acrylonitrile, acrylamide, and methylacrylate under conditions of acid catalysis takes place at the sulfur atom.The formation of minor amounts of N-derivatives is attributed to izomerization of the principal reaction products.
BENZAZOLIN-2-THIONES IN THE MICHAEL REACTION. 2. REACTION OF BENZOTHIAZOLIN- AND BENZOXAZOLIN-2-THIONES WITH ACRYLONITRILE, ACRYLAMIDE, AND METHYL ACRYLATE IN THE PRESENCE OF BASIC CATALYSTS

Depending on the structure of the reagents and the kind of basic catalyst, the addition of benzazolin-2-thiones to an activated double bond takes place at either nitrogen or sulfur.Acrylonitrile, regardless of the catalyst, reacts at the nitrogen atom.In the presence of sodium methylate, addition to acrylamide takes place only, and to methyl acrylate predominantly at nitrogen.In the presence of triethylamine, a mixture of compounds with a high content of S-derivatives forms.
