Oxidation of Mixtures of Thioureas: Part XII –Oxidation of Mixtures of 1,3-diaryl Thioureas and Thiourea Forming 1,2,4,-thiadiazolines
In an acidic alcoholic solution, binary combinations of 1,3-diaryl thioureas and thiourea create 3-amino-4-aryl-5-arylimino-D2-1,2,4,-thiadiazolines. The steric effect is responsible for the transformation of bis(formamidine)sulphide to amidinothiourea derivative. 3-amino-4-aryl-5-(2′,6′-xylyl)imino-D2-1,2,4,-thiadiazoline is obtained by oxidising binary mixes of 1-aryl-3-(2′,6′-xylyl)thiourea and thiourea in acidic alcoholic solution. The study also includes 1-aryl—(2′,5′-xylyl)thiourea and 1-aryl-3-(2′,5′-(diisopropyl phenyl)thioureas.
