An efficient and convenient heterogeneous catalytic procedure has been developed for the phosphonation of a-amino CH bonds with various dialkyl phosphites and diarylphosphine oxidesusing molecular oxygen as a sustainableoxidant over CoNiFe hydrotalcite. The catalytic system could tolerate various tetrahydroquinoline derivatives, and the corresponding a-amino phosphonic compounds could be obtained
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
A photoelectrochemical cell is able to save nearly 90% external bias input to realize activation of P–H/C–H bonds for cross-coupling hydrogen evolution as compared with an electrochemical cell.
