| abstract | The invention comprises compounds of the formula <FORM:1124646/C2/1> where R4, R5 and R6, which may be the same or different, represent alkyl radicals which may be interrupted by ether oxygen atoms, aryl radicals, cycloalkyl radicals or aralkyl radicals, at least one of which radicals is substituted by an isocyanate group, which radicals may be further substituted by other groups. The compounds are prepared by reacting an amine of the formula <FORM:1124646/C2/2> or the hydrochloride or carbamate thereof, in which R1, R2 and R3, which may be the same or different, represent alkyl radicals which may be interrupted by ether oxygen atoms, aryl radicals, cycloalkyl radicals or aralkyl radicals, at least one of which radicals is substituted by a primary amino group, which radicals may be further substituted by other groups, with phosgene. Specified substituents include chlorine and bromine and thioether, nitrile, sulpho, sulphonic acid ester, carboxylic acid ester, alkoxy, phenoxy, sulphene and further carbamate groups. Phosgenation is effected by known methods, e.g. the cold phase-hot phase process. A reaction solvent may be used. The amino urethane reactants may be prepared by reduction of the corresponding nitro-, cyano- or carbamoyl-urethanes. |
