Direct Aniline Formation with Benzene and Hydroxylamine
Chemistry, 2023 A single-step method for aniline formation was examined. Using a vanadate catalyst with an iron oxide co-catalyst and hydroxylamine hydrochloride as the amine source, an up to 90% yield of aniline was obtained with high selectivity.
