PROCESS FOR THE PREPARATION OF PHOSPHORIC ESTERS AND THIO PHOSPHORIC ESTERS

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....
