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。
