How is Thioperoxydicarbonimidic diamide hydrochloride (CAS: 14807-75-1) typically synthesized?

Thioperoxydicarbonimidic diamide hydrochloride (CAS: 14807-75-1) is typically synthesized by the reaction of thiocarbonyl dimer with ammonia followed by the addition of hydrochloric acid. This involves the condensation of dithiocarbonyl compounds with ammonia to form thiocarbimidic diamide, which is then treated with hydrochloric acid to produce the hydrochloride salt. The reaction conditions are carefully controlled to ensure high yield and selectivity.
