Greenhalgh, Colin W.; Shand, Charles A.; Thomson, Ronald H. published the artcile< The conjugated N,N'-(polyenediylidene)bissulfenamide chromophore. Part I. N,N'-bis(arylthio)quinone diimines>, Electric Literature of 112-63-0, the main research area is arylthioquinone imine; phenylenediamine sulfuration benzenesulfenyl chloride.
A series of bis(arylthio)quinone diimines were prepared by condensation reaction of sulfenyl chlorides with phenylenediamines in the presence or absence of pyridine, by condensation reaction of dichloroquinone diimine with thiols, or by substitution reaction of other bis(arylthio)quinone diimines. E.g., PhSCl reacted with C6H4(NH2)2-1,4 in CH2Cl2 containing pyridine for 30-60 min to give 43% diimine I (R = H). I (R = Me) was prepared in 10% yield by reaction of 4-MeC6H4SH with diimine II in dioxane for 30-60 min. The bis(arylthio)quinone diimines are potential dyes for synthetic fibers, having a yellow to violet coloration in solution
