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 <=30≦̸C with rapid stirring, and the mixt. was kept 5 h to give 64% (4-O2NC6H4O)PO; similarly prepd. were 90% (4-O2NC6H4O)3PS, and 77% (BuCHEtCH2O)3PO.
