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).
reported for the denitrosation of aryl-N-nitrosamines under mild reaction conditions using ethanethiol and PTSA. The reactions proceeds at roomtemperature and the amines are obtained in good to excellent yields. Many functional groups that are susceptible to reduction were stable during the denitrosation. A broad substrate scope and easy operations are salient features of this method.
