WebJun 17, 2024 · In contrast to the literature methods, we developed a procedure involving a robust work-up. According to our method, the mixture of benzaldehyde derivative and dialkyl phosphite is heated in the presence of 10% of triethylamine as the catalyst in a minimum quantity of acetone as the solvent (Scheme 1, Table 1). [Citation 17] Reactions Phosphites are oxidized to phosphate esters: P(OR)3 + [O] → OP(OR)3 This reaction underpins the commercial use of some phosphite esters as stabilizers in polymers. Alkyl phosphite esters are used in the Perkow reaction for the formation of vinyl phosphonates, and in the Michaelis–Arbuzov reaction to … See more In organic chemistry, a phosphite ester or organophosphite usually refers to an organophosphorous compound with the formula P(OR)3. They can be considered as esters of an unobserved tautomer phosphorous acid, … See more From PCl3 Phosphite esters are typically prepared by treating phosphorus trichloride with an alcohol. For alkyl alcohols the displaced chloride ion can attack the phosphite, causing dealkylation to give a dialkylphosphite … See more • Phosphinite P(OR)R2 • Phosphonite P(OR)2R • Ortho ester CH(OR)3 See more Diorganophosphites are derivatives of phosphorus(V) and can be viewed as the di-esters of phosphorous acid ((HO)2P(O)H). They exhibit tautomerism, however, the equilibrium overwhelmingly favours the right-hand (phosphonate-like) form: See more graph paper area
