Selective acylation of a symmetrical diamine with a dichlorotriazinyl
reactive dye would enable novel bis-monochlorotriazinyl dyes to be syn
thesised, and facilitate the manipulation of dye sunstantivity and hue
. We have succeeded in monoacylating p-phenylenediamine, in acid solut
ion, with the dichlorotriazinyl dye CI Reactive Red 1 in high yield. N
o bis-acylated product was observed by highperformance liquid chromato
graphy. Further reaction of the monoacylated product, with a different
dichlorotriazinyl compound, yielded a novel bis-monochlorotriazinyl d
ye.
