A mild method for the facile removal of phosphine oxide from the crude products of Wittig and Appel reactions is described. Work-up with oxalyl chloride to generate insoluble chlorophosphonium salt (CPS) yields phosphorus-free products for a wide variety of these reactions. The CPS product can be further converted into phosphine.
描述了一种温和的方法,可以方便地从Wittig和Appel反应的粗产物中去除磷烷氧化物。使用草酰氯进行后处理,生成不溶的氯磷铵盐(CPS),从而为多种反应提供无磷产品。CPS产物可以进一步转化为磷烷。
