Photocatalytic Cyclization of 2‑Phosphinobiaryls to Trivalent Dibenzophospholes

Photocatalytic Cyclization of 2‑Phosphinobiaryls to Trivalent Dibenzophospholes

This work demonstrates the photocatalytic cyclization of 2-phosphinobiaryls to dibenzophospholes. Using mild conditions, readily available 2-phosphinobiaryls were converted into trivalent <i>P</i>-alkyl- and <i>P</i>-aryl-dibenzophospholes. In this process, a <i>P</i...
