Let there be light: A heterogeneous photocatalytic system based on easily recyclable TiO2 or ZnO allows cross dehydrogenative coupling reactions of tertiary amines. The newly developed protocols have successfully been applied to various CC and CP bond‐formingreactions to provide nitro amines as well as amino ketones, nitriles and phosphonates.
A scalable, efficient gold‐catalyzed oxidativephosphonation of sp3CHbonds with various diarylphosphine oxides and dialkyl phosphites has been developed by usingair as a sustainableoxidant under mild reaction conditions. It provides an easy access to α‐amino phosphonic compounds in high yields with a broad reaction scope. The safe, convenient and environmentally benign process makes this protocol
