N,N′-Diaryldihydrophenazines as Visible-Light Photocatalysts for Anilines’ Arylation Using a Dual Photoredox/Ni(II) Cross-Coupling Strategy

It has been shown that cheap and easily available N,N′-diaryldihydrophenazines can successfully replace Ir(III)- and Ru(II)-based photocatalysts in the dual photoredox/Ni(II) C–N coupling of aryl halides with a wide range of anilines (32 examples). The efficient, operationally simple approach to diarylamines has been elaborated, which is amenable to scaling up via a flow apparatus.
