Herein we report a novel and straightforward protocol for the construction of valuable gem-BPs by means of proton-coupled electron-transfer (PCET)-triggered enamido C(sp2)?H diphosphorylation. This reaction represents a rare example of realizing the challenging double C?P bond formation at a single carbon atom, thus providing facile access to a broad variety of structurally diverse bisphosphonates from simple enamides under silver-mediated conditions. Initial mechanistic studies demonstrated that the diphosphorylation involves two rounds of PCET-initiated radical relay process.

A green organic synthetic method combining reductive acylation of ketoximes and oxidative coupling of terminal alkynes was developed. This novel process enables enamides and 1,3-diynes to be synthesized simultaneously in high yields and under mild conditions without the use of terminal reductants/oxidants.
