Abstract
Aromatic thioacylamides wherein the acyl group is aliphatic are prepared by treating in the absence of water the acyl derivative of an aromatic amine with a phosphorus halogen compound wherein the phosphorus is pentavalent, and treating the products without isolation with hydrogen sulphide in the presence of an inert solvent to form the corresponding thioacylamides. Suitable inert solvents are ether, benzene, carbon tetrachloride or chloroform, and the treatment with hydrogen sulphide is advantageously carried out with cooling of the reaction mixture. When the starting materials contain other reactive groups such as hydroxy or amino these are first protected by treatment with a toluenesulphonamide. In examples, the following acylamides are converted to thioacylamides by treatment with phosphorus pentachloride followed by hydrogen sulphide, the inert solvent being benzene and cooling of the reaction mixture being specified in some cases:--phenacetin, acetyl-p-anisidine, acetyl-o-toluidide, acetyl-m-xylidine, acetamidohydroquinone dimethylether (reduction and acetylation of nitrohydroquinone dimethylether), 5-acetylaminotrimethylpyrogallol, m-nitroacetanilide, 1.3- and 1.4-diacetylphenylenediamines, diacetylbenzidine, propionanilide, 2-acetylnaphthylamine, 4-acetylamino-1-methyl-naphthylamine, 4-acetylaminonaphthyl-methyl-and ethyl-ethers, 1-acetylamino-2-naphthyl ethyl ether, 2-acetylaminofluorene, 2-acetylaminodiphenyleneoxide, 5 - acetylaminoacenaphthene. The conversion of acetyl - o - anisidine, acetylaminophenanthrene, and 1-alkoxy - 2 - acetylaminonaphthalene is also mentioned. The products are useful for conversion to thiazole and thence to cyanine dyes Specifications 322,184, [Class 2 (iii)], and 351,557 are referred to.
