About the Reversible Conversion of 3-Diethylamino-5-phenyl-1,2,4-dithiazoliumhalometallates into Metal Chelates of 3-(Thio)benzoyl(thio)ureasRedox reactions of 3-diethylamino-5-phenyl-1, 2,4-dithiazolium halometallates 1a-e and metal chelates (M = CuII (2 A), CoII (2 C), NiII (2 F)) of 3-thiobenzoylthioureat was studied by cyclic voltammetry. 1 are converted by reduction into 2. The mechanism of the oxidation of 2 A, C, F into 1a, d, e is dependent on the central ion.On formation of 1 a from copper(II) chelates of 3-benzoylthiourea 3 A by means of thionylchloride as well as by electrochemical oxidation 3-benzoylureas 4 A are formed as sideproducts.
