Abstract
1,234,289. Production of N,N<SP>1</SP> - disubstituted thioureas. BADISCHE ANILIN- & SODAFABRIK A.G. 11 Oct., 1968 [12 Oct., 1967], No. 48224/68. Heading C2C. N,N<SP>1</SP> - Disubstituted thioureas of the formula in which the individual radicals R may be identical or different and each denotes an aliphatic, araliphatic, cycloaliphatic or aromatic radical (which radicals may be substituted by inert substituents), are obtained by reacting a formaldimine of the formula R-N=CH 2 with elemental sulphur and a primary amine of the formula R-NH 2 . The reaction is generally effected at 20-200‹ C., optionally in the presence of an inert organic solvent, and at least 2 gram atoms of sulphur is preferably employed per mole of formaldimine. Specific examples describe the preparation of N,N<SP>1</SP> - di - n - butyl-, N,N<SP>1</SP> - dicyclohexyl-, N,N<SP>1</SP> - dibenzyl- and N,N<SP>1</SP> - diisopropyl - thiourea.
