| Abstract: | The reaction of dilithiated N,N′-dimethyl-1,2-diphenylethylenediamine with disulfur dichloride (S2Cl2) gave a thiosulfinyl compound (R2N)2S S, 2,5-dimethyl-3,4-diphenyl-1,2,5-thiadiazolidine 1-sulfide, whereas the treatment of dilithiated N,N′-bis(p-toluenesulfonyl)-1,2-diphenylethylenediamine with S2Cl2 furnished a new heterocycle, 3,6-bis(p-toluenesulfonyl)-4,5-diphenyl-4H,5H-1,2,3,6-dithiadiazine. |
