The Co–N coordination in CoNx@NC (NCN-doped carbon) was found to be beneficial in producing high conversion efficiency and high yield for secondary amines in the N-alkylation reaction between alcohol and aniline.
A process for producing an aryl carbamate of a high purity at a high yield by reacting a diaryl carbonate with an amine compound having one or more hydrogen atoms bonded to the N position in the presence of carboxylic acid(s) of the following general formulae (I): R1-COOH and/or (II): R2-COOH (wherein R1 represents an alkyl or cycloalkyl group having a carbon atom at the α-position, which is bonded to only one hydrogen atom, and R2 represents an alkyl group having a carbon atom at the α-position, which is not bonded to a hydrogen atom).
