deuterium isotope exchange reaction in deuterated solvents. Under basic conditions, ionic liquid 1 was reactive and 50% deuterium exchanged on all four P–CH2 methylene groups in 9 h at ambient temperature, 30 min at 50 °C, or 12 min at 65 °C. In addition, ionic liquid 1 reacted with sodium salts of substituted benzoates apparently through the direct SN2 carboxylate alkylation to form esters 2 and the
