Abstract

Thiolcarbamic esters are manufactured by bringing into interaction an S-ester of thiolchloroformic acid, of the formula R(SCOC1)m, and a primary amine R1(NH2)n (or a salt thereof), wherein R and R1 represent hydrocarbon radicals, substituted or unsubstituted, the same or different, m is 1 or 2 and n is 1, 2, 3, 4 or 5, in the presence of an acid-binding agent which does not react with an S-ester of thiolchloroformic acid under the conditions of the reaction, e.g. an inorganic acid-binding agent such as sodium hydroxide or an organic acid-binding agent such as a tertiary amine or a metal salt of an organic acid. The reaction is preferably carried out at 0-10 DEG C., and conveniently in the presence of a solvent, which, when the primary amine is used in the form of a water-soluble salt, is preferably water. In examples: (1) p-tolyl thiolchloroformate is stirred with heptadecylamine in ethyl alcohol in the presence of dimethylaniline to produce p-tolyl heptadecylthiolcarbamate; the heptadecylamine may be replaced by p-aminophenol, m-phenylenediamine or a -naphthylamine; (2) ethylenediamine similarly (but using benzene as solvent) yields di-p-tolyl ethylene-bis-(thiolcarbamate); the ethylenediamine may be replaced by hexamethylene diamine, 1 : 3 : 5-triamino-2 : 4 : 6-triethylbenzene or aniline; (3) a -naphthylamine is treated as in (1), except that sodium acetate or sodium hydroxide is used as the acid-binding agent, producing p-tolyl a -naphthylthiolcarbamate; (4) aqueous sulphanilic acid similarly (using sodium hydroxide) gives p-tolyl p-sulphophenylthiolcarbamate; (5) p-aminobenzoic acid or b -alanine is treated as in (4) to produce p-tolyl p-carboxyphenyl- or b -carboxyethyl-thiolcarbamate; (6) ethyl thiolchloroformate and ethylenediamine are reacted as in (1) to form diethyl ethylene-bis-(thiolcarbamate); (7) p-tolyl thiolchloroformate is stirred with aniline in ethyl alcohol in the presence of triethylamine to yield p-tolyl phenylthiolcarbamate; (8) the ethyl alcohol and triethylamine in (7) are replaced by petroleum ether and pyridine; (9) m-phenylene-bis-(thiolchloroformate) is stirred with aniline in benzene in the presence of dimethylaniline to form m-phenylene-bis-(phenylthiolcarbamate); (10) 4 : 41 : 411-triaminotriphenylmethane trihydrochloride is stirred with p-tolyl thiolchloroformate in aqueous solution in the presence of dimethylaniline to give tri-p-tolyl triphenylmethane-4 : 41 : 411-tris-(thiolcarbamate); the triaminotriphenylmethanetrihydrochloride may be replaced by 2 : 4 : 31-triaminostilbene trihydrochloride, 2 : 4 : 21 : 41-tetraminostilbene tetrahydrochloride or 2 : 4 : 21 : 41 : 311-pent amino-5 : 51-dimethyltriphenylmethane pentahydrochloride; (11) ethyl thiolchloroformate is treated as in the first part of (10) to produce triethyl triphenylmethane - 4 : 41 : 411 - tris - (thiolcarbamate). Additional amines specified are ethyl p-aminobenzoate and 1 : 5-pentanolamine. 1 : 3 : 5-Triamino-2 : 4 : 6-triethylbenzene is obtainable by hydrogenating 1 : 3 : 5-trinitro-2 : 4 : 6-triethylbenzene.
