Abstract
The conditions for the synthesis of thiazan-2,4-diones by the condensation of β-chloropropionic, β-chloro- and β-bromobutyric, and β -chloroisobutyric acids with thiourea in acetic anhydride, water, and formic and acetic acids were studied. S-Guanylmercaptohydracrylic acids, 2-imino- and 2-acetyliminothiazan-4-ones and their hydrochlorides, and thiazan-2,4-diones were isolated. Their interconversions were studied.
