Decarboxylative Selective Phosphorylation of Aliphatic Acids: A Transition‐Metal‐ and Photocatalyst‐Free Avenue to Dialkyl and Trialkyl Phosphine Oxides from White Phosphorus
Functionalization of white phosphorus (P4) with N-hydroxyphthalimide esters to synthesize dialkylphosphines and trialkylphosphines under transition-metal- and photocatalyst-free conditions is presented. The oxidation products can be isolated in high yield via the air oxidation of alkylated phosphines.
