strategy of various phosphates has been developed. This method enables the facile synthesis of functional phosphates such as alkyl phosphates, aza phosphates, thiophosphate, and mixed diaryl phosphates. A transient phosphorylpyridin-1-ium species in situ generated fromphosphates with Tf2O/pyridine readily undergoes a substitution reaction with diverse nucleophiles to form versatile phosphate compounds.
已开发出各种磷酸盐的无金属,无毒氯化物试剂的活化策略。该方法使得能够容易地合成功能性磷酸盐,例如烷基磷酸盐,氮杂磷酸盐,硫代磷酸盐和混合的二芳基磷酸盐。由具有Tf 2 O /吡啶的磷酸盐原位产生的瞬时磷酰吡啶-1-鎓物质很容易与各种亲核试剂发生取代反应,形成通用的磷酸盐化合物。

Organophosphorus (OP) chemicalwarfare agents (CWAs) represent an ongoing threat but the understandable widespread prohibition of their use places limitations on the development of technologies to counter the effects of any OP CWA release. Herein, we describe new, accessible methods for the identification of appropriate molecular simulants to mimic the hydrogen bond accepting capacity of the PO moiety

A number of N-phosphoryl oxazolidinones have been prepared and evaluated, the best being 5,5-diphenyl oxazolidinones, the utility of which was demonstrated in the phosphorylation of a number of representative primary, secondary, tertiary, and phenolic alcohols.
