ABSTRACT OF THE DISCLOSURE A new group of compounds, generically classed as phenothiazinyl sulfides, are described having the formula: Image wherein n is 1 or 2, x and/or y and/or z represent 0, 1 or 2; R1 may be H, alkyl, aryl, alkaryl, acyl, haloacyl and biologically activating aminoalkyl groups known in the medicinal arts, such as -(CH2)3-N(CH3)2, Image , Image , Image , and -[2-(1-methyl-2-piperidyl)ethyl]; and R2 and/or R3 and/or R4 and/or R5 and/or R6 and/or R7 represent H, OH, Cl, Br, F, CF3, SN, NO2, CN, COOH, alkyl, alkoxy, sulfamoyl, dimethylsulfamoyl, dimethyl amino, aryl, alkaryl, acyl, aryloxy, methyl sulfonyl, methyl thio, and -S-phenothiazinyl substituents; and as charge-transfer complexes of iodine therewith in which the number of moles of iodine associated with the molecule equals 1.5 (range 0.75 to 3.0) times the number of phenothiazinyl groups in the molecule. Methods for the preparation of the compounds are de- scribed. The phenothiazinyl sulfides appear to be active in the same industrial and biological applications as phenothiazine and its corresponding derivatives, and show distinctive activity in various uses and as charge-transfer complexes of novel electro- chemical properties as illustrated, in vitro, in combination with iodine as a cathode material.
