摘要：

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