Abstract
Abstract The reaction of dilithiated N , N ′-dimethyl-1,2-diphenylethylenediamine with disulfur dichloride (S 2 Cl 2 ) gave a thiosulfinyl compound (R 2 N) 2 S 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 S 2 Cl 2 furnished a new heterocycle, 3,6-bis( p -toluenesulfonyl)-4,5-diphenyl-4 H ,5 H -1,2,3,6-dithiadiazine.
