Abstract

The present preliminary report clearly justifies more detailed examinations of this previously unreported oxidative technique. AgO may prove to be a general reagent for oxidizing thiono-organophosphorus pesticides to their phosphates which are often more potent ChE inhibitors than the parent compounds; many other oxidants have been utilized for this purpose with reported conversion efficiencies ranging from a few percent to near quantitative, usually on a macro-scale; most micro methods in the literature are of very low efficiencies. Whether AgO will also oxidize any of the thiolo-organophosphorus compounds to their phosphates is not yet established, except for negative results with Thimet.

摘要

本初步报告清楚地证明了对这种以前未报道的氧化技术进行更详细检查的合理性。AgO 可能被证明是一种将硫代有机磷杀虫剂氧化为其磷酸盐的通用试剂,而这些磷酸盐通常比母体化合物更有效地抑制 ChE;为此目的,已经使用了许多其他氧化剂,其转化率从百分之几到接近定量,通常在宏观尺度上;文献中的大多数微量方法的效率都非常低。AgO 是否也会将任何硫醇有机磷化合物氧化为其磷酸盐,目前还不确定,只有与 Thimet 的结果为阴性。
