different Grignard reagents giving, in a very fast and in a highly selective manner, only one phosphorus-containing compound with an enormous rate enhancement with respect to the corresponding no-catalyzed reaction which gives a final cluttered mixture of many organophosphorus products. The focal factor to explain this highly selective process of P transport lies in the folded structure of the reagent with
摘要 描述了一种简单且非常快速的磷原子转移过程,该过程由作为催化剂的简单分子在几乎无限的催化循环中进行。该催化剂将一个 P 原子提供给两种不同格氏试剂的混合物,以非常快速和高度选择性的方式,仅产生一种含磷化合物,相对于相应的无催化反应,具有极大的速率提高,从而产生许多有机磷产品的最终杂乱混合物。解释这种高选择性 P 传输过程的焦点因素在于试剂的折叠结构,围绕磷原子具有特定角度,这可以促进环状三方双锥五配位物质的形成,进而促进其催化活性。以类似的方式,RNA 可以采用,在一个精确的位置,一个特定的三维结构,可能有助于形成导致催化功能的五配位物种。图形概要
