reactions can produce freeradicals duringmetabolism, which start chain reactions and damage cells.Antioxidants terminate these chain reactions by removingfree radical intermediates, and also inhibit other oxidationreactions. In recent years, a detailed mechanism of the antioxidantaction of organophosphorus compounds and their relation-ships between chemical structure and antioxidant activityhas been comprehensively

Choline hydroxide has been found to be an efficient basic ionic liquid catalyst for the synthesis of α-hydroxyphosphonates. Hydrophosphonylation of aldehydes was performed via the nucleophilic addition of diethylphosphite to aldehydic carbonyl compounds, in the presence of choline hydroxide under neat as well as solvent conditions. A wide array of substrates, including aromatic, fused aromatic, and
