| titleOfInvention | Process for preparing esters of thiolcarbamic acids |
| abstract | The invention relates to a new process for preparing known thiolcarbamate esters of the general formula (I) <IMAGE> (I) wherein R1 and R2 stand independently for hydrogen or a straight or branched chain alkyl group containing 1 to 6 carbon atoms or an alkenyl group containing 2 to 6 atoms, or an alkyl group containing 1 to 6 or an alkenyl group containing 2 to 6 carbon atoms and mono- or polysubstituted by halogen, oxygen, sulphur and/or nitrogen; or R1 and R2 together may represent an optionally substituted alpha , omega -alkylene group containing 4 to 6 carbon atoms; R3 and R4 stand independently for hydrogen or an alkyl group containing 1 to 4 carbon atoms and optionally substituted by halogen or by a group containing oxygen, sulphur and/or nitrogen; and R5 and R6 both stand for hydrogen; or R5 and R6 together may represent a chemical bond. The compounds of general formula (I) are prepared by reacting (a) thiolcarbamate salts of the general formula (II) <IMAGE> (II) wherein the meanings of R1 and R2 are as defined above, and Y stands for a primary, secondary or tertiary ammonium ion or an alkaline metal ion; or (b) amines of the general formula (III) <IMAGE> (III) wherein the meanings of R1 and R2 are as defined above, together with sulphur and carbon monoxide; or (c) amine of the general formula (III) together with carbonyl sulphide with alkynes of the general formula (IV) R3-C 3BOND C-R4 (IV) wherein the meanings of R3 and R4 are as defined above and, if desired, hydrogenating the obtained product of general formula (I), wherein the meanings of R1, R2, R3 and R4 are as defined above and R5 together with R6 forms a chemical bond, to a compound of the general formula (I), wherein both R5 and R6 stand for hydrogen. |
