标题:长期寻求从氧化膦合成季phospho盐的方法:逆反应法†
摘要:季phospho盐(qps)是一类重要的有机磷化合物,以前只能通过涉及亲核性磷的途径获得.我们报告了利用膦氧化物作为亲电子伴侣和格氏试剂作为亲核试剂实现qps的相反方法的实现.通过衍生的卤化salts盐的关键中间体来实现该过程.该路线不受动力学慢和许多母体膦的有限供应的困扰,并且以优异的收率制备了多种qps.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.
