Hydrogen peroxide oxidation of a mixture of 1-alkyl-3-arylthiourea and thiourea in acidic alcoholic solution yields two isomeric 3-amino-1,2,4-thiadiazolines (VI and VII) via amidinothiourea.The rearrangement of the intermediate bis(formamidine)sulphide to the amidinothiourea derivative has been found to be governed by the steric effect.
