Popis:	The treatment of 4- and 5-hydroxylaminothiazolidine-2-thiones as well as 5-hydroxylaminothiazolidin-2-one with acetic anhydride or benzoyl chloride is accompanied, as a rule, by the formation of O-acyl derivatives. The 4-(O-acyl) derivatives are thereby either stable to thermal or alkaline treatment, or are converted to 4-iminothiazolidine-2-thione; the 5-(O-acetyl)-hydroxylamines rearrange to 6-thioxo(oxo) derivatives of 4,5-dihydro-6H-1,2,5-thiadiazine.
