The C(sp3)–P bond is formed via the reaction between P–H compounds and non-activated alkyl electrophiles, especially secondary alkyl halides and tosylates. This reaction proceeds via an SN2 mechanism with inversion of configuration, so it can be used to form C–P bonds with stereocontrol from chiral secondary alcohols.
C(sp 3)-P键是通过P–H化合物与未活化的烷基亲电试剂(特别是仲烷基卤化物和
甲苯磺酸酯)之间的反应形成的。该反应通过具有反转构型的S N 2机理进行,因此可以用于从手性仲醇的立体控制下形成C-P键。
