Two haptens of the insecticide triazophos (O,O-diethyl O-[1-phenyl-1H-1,2,4-triazol-3-yl] phosphorothioate) were synthesized by introducing appropriate spacers in the O-ethyl site of the analyte molecular structure. First, thiophosphoryl chloride (PSCl(3)) reacts with methanol at low temperature to give O-ethyl dichlorothiophosphate. After reacting...

Elemental [35S]sulfur was shown to equilibrate with the sulfur of thiophosphoryl chloride when these materials are heated together. This isotopic exchange reaction is the basis of a convenient, microscale synthesis of high specific activity [35S]PSCl3. [35S]Thiophosphoryl chloride is otherwise not...
