“…In contrast to these findings Ross and Smith reported in 1964 that KCN and SO 2 react in the absence of hydroxylic solvents with formation of potassium 3-cyanohydroxy-1,2,5-thiadiazolate (eq 2). 7 The heterocyclic compound was characterized by infrared spectroscopy and degradation reactions. Moreover, an independent synthesis from isonitrosocyanoacetamide and sulfur dichloride yielded the same product.…”

“…was obtained by reacting tellurium(IV) bromide with a tetraphenyltin in boiling toluene [9], m. p. 199°C. Nitroso carbamylcyanmethanide was prepared by the method of Ross [10] and an aqueous solution of the anionic lig and was prepared by stoichiometric reaction with a solu tion of CS2CO3. The silver salt of nitrosocarbamylcyan methanide, Ag{ACO}, was obtained by ion exchange re action with AgNOi.…”

“…These studies have encompassed, among other compounds, the remarkably stable, completely enolic, 3-hydroxy derivatives. The corresponding 3-mercapto compounds have not heretofore been described, although at least one unsuccessful attempt to prepare such substances has been reported (3). This publication describes the synthesis of stable salts of two 3-mercapto-1,2,5-thiadiazoles, one of which is the parent member of the series.…”
