Phosphorus compounds are ubiquitous in the chemical sciences, finding applications throughout industry and academia. Of particular interest to synthetic chemists are organophosphorus compounds, which contain P-C bonds. However, state-of-the-art processes for the synthesis of these important materials rely on an inefficient, stepwise methodology involving an initial oxidation of white phosphorus (P-4) with hazardous chlorine gas and the subsequent displacement of chloride ions. Catalytic P-4 organofunctionalization reactions have remained elusive, as they require multiple P-P bond-breaking and P-C bond-forming events to break down the P-4 core, all of which must occur in a controlled manner. Herein, we describe an efficient transition-metal-catalysed process capable of forming P-C bonds from P-4. Using blue-light photocatalysis, this method directly affords valuable triarylphosphines and tetraarylphosphonium salts in a single reaction step.
