Abstract
The invention comprises compounds of the general formula NC(A)N = C = S wherein A represents an alkylene radical having from 2-14 carbon atoms, the chain being either straight or branched, and the preparation thereof wherein (A) a cyanoalkamine is reacted with carbon disulphide in the presence of a tertiary amine, preferably triethyamine, and in an inert solvent, preferably an inert chlorinated solvent such as chloroform, to form the corresponding cyanoalkyldithiocarbamate salt, ethyl chloroformate is added to form the carbethoxy cyanoalkyldithiocarbamate which is decomposed by the addition of one mol. equivalent of a tertiary base to give a cyanoalkylisothiocyanate; or (B) a cyanoalkamine is reacted with carbon disulphide in the presence of a tertiary amine such as triethylamine, and in an inert solvent, preferably an inert chlorinated solvent such as methylene chloride, to form the cyanoalkyldithiocarbamate salt which is oxidized with sodium hypochlorite to form the cyanoalkylisothiocyanate. Examples are given of the preparation of the following compounds either by method (A) or (B) or both: 2-cyanoethyl-, 1-methyl-2-cyanoethyl -, 2 - cyanopropyl -, 3 - cyanopropyl -, 4 - cyanobutyl -, 5 - cyanopentyl -, 6-cyanohexyl -, 10 - cyanodecyl -, and 14 - cyanotetradecylisothiocyanates. The Provisional Specification relates to compounds of the general formula CN(CH2)nN = C = S, in which n is an integer from 2 to 18 and the preparation thereof by treating the aminonitrile in aqueous solution at a temperature between 0 DEG and 20 DEG C. in the presence of one mol. equivalent of a base, for example ammonium, potassium or sodium hydroxide or triethylamine, with one mol. equivalent of carbon disulphide. No additional examples are given.
