PROCESS FOR THE PREPARATION OF PHOSPHORIC ESTERS AND THIO PHOSPHORIC ESTERS

Aryl or aliph. phosphate and thiophosphate esters were prepd. by treatment of a phenol with POCl3 or PSCl3 in the presence of an alkali metal carbonate or hydroxide, H2O, and an org. solvent. Thus, 139.1 g 4-O2NC6H4OH in 2000 mL Me2CO were treated with 55.2 g POCl3, then immediately treated with 96....

Zusammenfassung:Aryl or aliph. phosphate and thiophosphate esters were prepd. by treatment of a phenol with POCl3 or PSCl3 in the presence of an alkali metal carbonate or hydroxide, H2O, and an org. solvent. Thus, 139.1 g 4-O2NC6H4OH in 2000 mL Me2CO were treated with 55.2 g POCl3, then immediately treated with 96.0 g 45% NaOH over 10 min at
