Anti-Markovnikov oxidation of terminal aryl alkenes to aldehydes and transformation of N-methyl aryl tertiary amines to formamides with H2O2 as a terminal oxidant under mild conditions have been achieved with moderate to good product yields using [Fe(III)(TF4DMAP)OTf] as catalyst.
added Lewisacids like Zn2+ through a plausible chloride or OTf− bridge, which has promoted the redox potential of iron(III) species. The amine oxidation mechanism was also discussed based on the available data, which resembles the co-oxidase activity of lipoxygenases in oxidative dealkylation of xenobiotic metabolisms where an external electron donor is not essential for dioxygen activation.

A series of aromatic and aliphatic aldehydes was reacted with N-((p-nitrobenzenesulfonyl)oxy)methylamine in chloroform. Products resulting from both carbon migration and hydride migration to nitrogen were isolated. The ratios of carbon to hydride migration products were used to clarify the reaction mechanism. The results support a two-step process in which cationic carbon to nitrogen rearrangement is rate determining.
