Three p-phenylenediamine antioxidants (p-phenylenediamine-N,N,N',N'-tetrapropionic acid tetramethyl ester, p-phenylenediamine-N,N,N'-tripropionic acid trimethyl ester, and p-phenylenediamine-N, N'-dipropionic acid dimethyl ester) were successfully synthesized via atom-economic aza-Michael addition of pphenylenediamine to methyl acrylate p-romoted by graphene oxide in water. The synthesized compounds were characterized by NMR, ESI-MS spectra, and elemental analyses. The effects of the solvent and graphene oxide on the reaction were investigated.
