AbstractThe covalent binding of two aromatic amines, 1‐naphthylamine and 4‐methylaniline, to substituted quinones in aqueous solutions has been studied as a model for the covalent binding of amines to humic acids. An inline compound was the only type of product identified for the reactions between 1‐naphthylamine and selected quinones. Reactions of 4‐methylaniline with the same quinones gave a 1,4‐ addition product in addition to the imine compound, although only the imine product was formed when the quinone had bulky substituents at the 2‐ and 6‐ positions. These results provide additional insight into the reactions of aromatic amines with humic acid quinones.

New methods for C–N bond construction exploiting the N-centered electrophilic character of iminoquinones are reported. Iminoquinones, generated in situ via the condensation of o-vinylanilines with benzoquinones, undergo acid-catalyzed cyclization to afford N-arylindoles in excellent yields. Under similar reaction conditions, homoallylic amines react analogously to afford N-arylpyrroles. Additionally
