this compound shows considerable pi-donor properties as the result of the rather strong +M effect of the CH3S-substituent, changing the electronic properties of this low-coordinate and aromatic phosphorus heterocycle substantially.
对于取代的
吡啶基官能化的次膦,已经观察到迄今为止前所未有的电子情况。与以前的研究相比,由于
CH3S取代基的强+ M效应,该化合物显示出显着的pi供体性质,从而大大改变了这种低配位和芳香族
磷杂环的电子性质。
