Metal-free visible light-induced cross-dehydrogenative coupling of benzocyclic imines with water/P(O)H compounds: efficient access to functionalized benzazepines/ones

A metal-free visible light-induced cross-dehydrogenative coupling of aldimines with nucleophiles in a one-pot fashion is first reported, which features high efficiency,the absence of external oxidants, and mild and redox-neutral reaction conditions.
