Diphenyl Phosphite is a reactant used in the synthesis of α-hydroxyphosphonates and α-hydroxyphosphinates for their antioxidant and antimicrobial activity.
Synthese

2310-89-6

108-95-2

4712-55-4

In a three-necked round-bottomed flask equipped with a mechanical stirrer, a reflux condenser and a dropping funnel, the first P-O component (PIII-OH) is added under nitrogen protection. This P-O component (see column 5 of Table 1) may be selected from H3PO3, monoalkyl phosphite or mixtures thereof and may additionally comprise dialkyl phosphite. Subsequently, the first P-O component is heated to the temperature specified in column 11 of Table 1 (T° step a) for step a). Next, the second P-O component (see column 6 of Table 1) is added while maintaining the appropriate temperature. The mixture was allowed to react for the time indicated in column 13 of Table 1 (reaction time step a), followed by step b). The alcohol R1-OH (see column 3 of Table 1) is then added dropwise while maintaining the temperature specified in column 12 of Table 1 (T° step b). After the mixture was reacted for the time indicated in column 14 of Table 1 (reaction time b), it was cooled to room temperature and analyzed by 31P NMR.
läuterung methode
Diphenyl Phosphite can be purified by distillation. Best done in small batches since decomposition frequently occurs. Phenol can be substantially removed by heating at 150 °C at water pump vacuum.
