| titleOfInvention | Process for the preparation of diaryliminocarbonates |
| abstract | Process for the preparation of iminocarbonic acid diaryl esters of the general formula I in the R¹ represents an alkyl, aminoalkyl, cycloalkyl, aralkyl, aryl group or a heterocyclic or heteroaromatic radical, Y and Z are the same or different and represent an alkyl, alkoxy, haloalkyl, aryl, cyano, nitro group or halogen, m and n represent an integer from 1 to 5, where, if m and n are greater than 1, the radicals Y and Z are the same or different, characterized in that diphenyl iminocarbonate II with a substituted phenol III at temperatures of 50 to 250 ° C to iminocarbonic acid diaryl esters IV and reacting the compounds IV after their isolation or in situ with a phenol substituted by Z or Y to give the end products I and new imino carbonic acid diaryl esters I and II and preparation of the diphenyl imino carbonic acid II by reacting dichlorodiphenoxime methane with a primary amine R 1 NH 2 in an inert solvent in the presence a base and optionally in the presence of a catalytic amount of N, N-dialkylaminopyridine. |
