Abstract

Dyestuffs are obtained by condensing by means of phosphorus oxychloride, a b -b <1>-di-indolylketone with a secondary or tertiary aromatic amine or with an indole substituted in the a position by a hydrocarbon radicle. The resulting dyestuffs may be used for colouring cellulose ester lacquers and when sulphonated are suitable for dyeing wool and silk. The secondary and tertiary amines may contain alkyl, alkoxy, aryl, aralkyl and acyl groups. In examples: (1) 4-methyl-3<1>-ethoxydiphenylamine is condensed in toluene with b : b <1>-di(N - methyl - a - phenylindolyl)ketone or b : b <1>-di-(a -methylindolyl)ketone; (2) a keto-chloride compound is first formed from b : b <1>-di-(N-methyl-a -phenylindolyl) ketone, by treatment in tetrachlorethane with phosphorus oxychloride, and 4<1>-3<1>-diethoxy- (or 4-ethoxy) diphenylamine condensed therewith; the resulting basic dyestuff on sulphonation gives a disulphonic acid which dyes wool and silk blue shades; (3) b : b <1>-di-(N-methyl-a -phenylindolyl) ketone is condensed with N-methyl-a -phenylindole and sulphonated to give a trisulphonic acid. b : b <1>-Di-indolylketones may be obtained by reacting two molecular proportions of a or N and a substituted indoles with one molecular proportion of phosgene in a solvent.
