Oxyamination of alkenes enabled by direct photoexcitation of fluorenone oxime derivatives

Abstract Visible-light-induced oxyamination of alkenes was developed using fluorenone oxime carbonate as a photoactivatable agent. The nitrogen atom was selectively incorporated at the internal position, constructing a sterically congested α-tertiary amine moiety. The reaction proceeded without any photocatalyst and in the presence of various additives with different functional groups, highlighting the simplicity and robustness of the protocol. Moreover, the fluorenone oxime motif proved effective for visible-light-induced decarboxylative carboamination and diamination of alkenes.
