A substantial improvement in the challenging photocatalytic arylation of white phosphorus (P-4) with aryl chlorides and bromides is reported. Using the readily accessible deazaflavin-based photocatalyst o-Me-dFl, valuable triarylphosphines (PAr3) and tetraarylphosphonium salts ([PAr4]X, X = Br, Cl) are synthesized from P-4 under near UV-LED (365 nm) irradiation in up to 87% combined yield with drastically reduced reaction times compared to previous protocols. P-31 nuclear magnetic resonance spectroscopic monitoring studies and density functional theory calculations provide insights into the reaction pathway. The results represent an important step toward more atom-efficient and economical photocatalytic P-4 functionalization reactions.
