A simple and efficient method for the cyclization of the addition of P-radical to 2-isocyano-1,1'-biphenyl by employing silver salt as an oxidant was developed. The high atom economy, mild reaction system and a wide range of substrates with high yields make the protocol very practical. It provides a new route for C-P bond formation. A series of 6-phosphorylated phenanthridines were synthesized.
