    • MANUFACTURE OF SUBSTITUTED PHENYL PHOSPHATES INVOLVING USE OF PHASE TRANSFER CATALYSTS Substituted phenyl phosphates, phosphonates, phosphinates, and thiono and thiolo derivatives thereof having the formula in which R is a member selected from the group con sisting of alkyl and alkoxy, R1 is a member selected from the group con sisting of alkyl, alkoxy, aryl, aralkyl, amino, and alkyl-substituted amino; X is oxygen or sulfur; Z is oxygen or sulfur; W is a member selected from the group con sisting of alkyl, alkoxy, alkylthio, nitro, halogen, and alkanoyl; and n is an integer from 0 to 3; are manufactured by a process which comprises reacting a phosphoryl halide of the formula in which Y is chlorine or bromine; with an alkali metal or alkaline earth metal salt of a compound having the formula in the presence of a catalytic amount of a phase transfer catalyst selected from the group consisting of macrocyclic polyethers and quaternary salts having the formula (R2R3R4R5M)+Qin which R2, R3, R4 3 and R5 taken individually are independently selected from the group consisting of alkyl, alkenyl, aryl, alkaryl, aralkyl, and cycloalkyl; or any two are joined to constitute a hexagonal or pentagonal heterocyclic moiety containing the M atom plus at most one non-adjacent nitrogen, oxygen, or sulfur atom; M is a member selected from the group con sisting of nitrogen, phosphorus, and arsenic; and Q is an anion selected from the group con sisting of halide, hydroxyl, bisulfate, perchlorate, nitrate, acetate, tosylate, benzoate, and carbonate ions.
