| abstract | Amides of diazonaphthol-sulphonic and carboxylic acids corresponding to the formul <FORM:0699412/IV (b)/1> in which R stands for the residue of 2-diazonaphthol- (1) or 1-diazo-naphthol- (2) and X, Y stand for hydrogen or substituents such as alkyl, aryl or aralkyl groups; and aliphatic or aromatic esters of the sulphonic or carboxylic acids of the 2-diazo-naphthol- (1) or 1-diazonaphthol- (2) are made by reacting the chlorides of these acids with organic hydroxy or amino compounds. Suitable hydroxy compounds are phenols, naphthols, 1-nitro-2-naphthol, N-benzyl - p - aminophenol, N - acetyl - or N - benzoyl - 1,5 - or - 2,8 - aminonaphthol, hy - droxyphenanthrenes, 2 - hydroxy - chrysene and hydroxynaphthimidazoles; and the amines may be N - methylaniline, N - ethylnaphthyl - amine, 2,4 - dichloraniline, p - phenetidene, p - aminodiphenylamine, aminofluorene, amino - diphenylene oxide or dodecylamine. The sulphochlorides concerned may be made by action of chlorsulphonic acid on the corresponding acids. Examples, as enumerated, describe reaction products of 2 - diazo - naphthol - (1) - 5 - sulphochloride or 2 - diazo - naphthol - (1) - 4 - sulphochloride with (1) 1 - benzoylamino - 5 - hydroxynaphthalene, 2 - benzoylamino - or 2 - acetylamino - 8 - hydroxynaphthalene; (2) 71 - hydroxy - 1,2 - naphthimidazole; (3) 2 - hydroxychrysene; (4) phenol; (7) 3 - benzoylamino - 1 - phenol; (8) N - methyl - 2 - hydroxycarbazole; (9) 3 - hydroxy - diphenylene oxide; (10) 2,4-dichlorophenol, N-methylaniline; (11) p - aminodiphenylamine, b - naphthylsulphonic acid; (12) 4 - aminobenzophenone; (13) 2 - amino - fluorene; (14) dodecylamine; (15) b - naphthylamine; (16) a - naphthol; (19) 2 - hydroxyfluorene; (20) b - naphthylamine, p - xylidine; (22) methyl - glycineethylester; (23) p - phenetidine; (24) p - toluidine; (26) p - cresol, p-nitrophenol. Example 5 describes preparation of 1-diazonaphthol-(2)-6-carboxylic acid anilide by diazotizing 1 - amino - 2 - hydroxy - 6 - naphthoic acid anilide.ALSO:The chlorides of sulphonic or carboxylic acids of 2-diazo-naphthol-(1) or 1-diazo-naphthol-(2) are reacted with 1- or 2-hydroxyanthraquinone. |
