No photocatalyst required--versatile, visible light mediated transformations with polyhalomethanes.

Johannes F Franz1, Wolfgang B Kraus, Kirsten Zeitler.   

Abstract

A visible light mediated, but photocatalyst-free method for the oxidative α-CH functionalization of tertiary amines with a broad scope of carbon- and heteroatom nucleophiles using polyhalomethanes has been developed. In addition, the pivotal visible light triggered activation of polyhalomethanes offers mild conditions for efficient Kharasch-type additions onto non-activated olefins. Preliminary mechanistic studies are reported.
