Abstract

Diphenylmethane mono and dicarbamates and polymethylene polyphenyl carbamate homologs and derivatives of these compounds are produced by the protonic or Lewis acid catalyzed rearrangement of an (alkoxycarbonyl) phenylamino methylphenyl compound having the general formula < IMAGE > (or a higher homolog of such a compound) wherein each of x, y and z, which may be different in each ring, is a hydrogen atom, an alkyl group having from 1 to 3 carbon atoms, an -NHCOOR, -CH2ArNHCOOR or -N(COOR)CH2Ar group, R is a 1 to 3 carbon alkyl group and Ar is phenyl which may be substituted with a 1 to 3 carbon atom alkyl group.
