WebApr 12, 2024 · Alkylphosphonates have found widespread applications in pharmaceuticals, agrochemicals, and materials science. However, methods for C(sp3)-phosphonylation remain underdeveloped. Herein, Wang, Zhu, Li, and coworkers demonstrate that the merger of photo-organocatalysis and copper catalysis enables the decarboxylative radical … WebA novel photoredox-neutral ring-opening pyridylation of non-prefunctionalized cyclic oximes has been accomplished through phosphoranyl radical-mediated N O/C C bond cleavages followed by radical-radical coupling. This mild acid-, base-, and oxidant-free protocol provides highly site-selective and efficient access to distally pyridylated alkylnitriles, which …
