O,O-二烃基二硫代磷酸酯,(RO)_2(?)—SH,是有机磷化合物中重要的中间体之一,通过它可以合成多种硫代磷酸酯类的化合物。虽然本世纪初便已肯定了这类化合物的结构,但是它的化学引起更多人的注意却是在发现了它的衍生物具有实用意义之后;特别是在发现了它的某些衍生物具有“高效低毒”及“内吸作用”的优异杀虫性能之后。 O, O-dialkyl dithiophosphates, (RO) _2 (?) - SH, is one of the most important intermediates in organophosphorus compounds. Many thiophosphate compounds can be synthesized by this method. Although the structure of this compound has been affirmed at the beginning of this century, its chemistry has attracted more attention after its usefulness was discovered. In particular, it was found that some of its derivatives have “ Efficient and low toxicity ”and“ systemic effect ”after the excellent insecticidal performance.
