Facile Synthesis of H-Phosphinates from P(OR)₃ or ClP(OR)₂ via SiO₂-Promoted Hydrolysis

-Phosphinates represent a valuable class of organophosphorus building blocks and catalytic ligands. The existing synthetic approaches are generally associated with the use of strong acids, the need for meticulous treatment of intermediates, and the limitation of only P-aryl introductions. Following a comprehensive investigation into the unexpected SiO
