  • ${\underline{O}},{\underline{O}}-Diethyl-{\underline{S}}-phenyl\;phosphorothiolate-^{18}O$ and other related compounds were prepared and oxidized with m-chloroperbenzoic acid (MCPBA). Each reaction was followed by $^{31}P$ NMR and the products were analyzed by GC-MS. ${\underline{O}},{\underline{O}}-Diethyl-{\underline{S}}-phenyl\;phosphorothiolate-^{18}O$ was converted to diethyl methyl phosphate in methanol by MCPBA and it was confirmed to contain $^{18}O$, which proved that the originally proposed mechanism of Segall and Casida operates in the oxidative reaction.
