A series of diverse NH- and CH-acids are used for a one-potsynthesis of stable phosphorus ylides and 1,4-diionic organophosphorus compounds by trapping of the zwitterionic intermediate from the reaction between triphenylphosphine and dialkyl acetylenedicarboxylates under solvent-free conditions. The structural geometry for one of the products was confirmed by single crystal X-ray diffraction analysis
一系列不同的 NH- 和 CH-酸用于通过在无溶剂条件下捕获三苯基膦和乙炔二羧酸二烷基酯之间反应的两性离子中间体,用于稳定磷叶立德和 1,4- 二离子有机磷化合物的一锅合成。通过单晶 X 射线衍射分析证实了其中一种产品的结构几何形状。补充材料可用于本文。转至出版商在线版的磷、硫和硅及相关元素,查看免费的补充文件。图形概要
