Reactions of Monoprotic Thioureas with Ethyl α-Chloroacetoacetate, Ethyl Bromomalonate, and Ethyl Bromocyanoacetate

N,N,-Dialkyl-N'-arylthioureas (1) with ethyl α-chloroacetoacetate, furnished dialkylamine hydrochlorides, aryl isothiocyanates, 2-arylimino-1,3-oxathioles (2), 2-arylimino-3-aryl Δ4-thiazolines (3), diarylthioureas (9), and carbonyl sulphide.With ethyl bromomalonate the products were dialkylamine hydrobromides, aryl isothiocyanates, 2-arylimino-3-arylthiazolidin-4-ones (11), and diarylthioureas (9).Ethyl bromocyanoacetate gave an ethyl cyanothio>acetate (13).Compound (13) with triethylamine gave the starting thiourea (1) and diethyl dicyanofumarate.
