Acyclic phosphoranes, ArnP(OR)5–n with n= 0–3 are shown to hydrolyse in neutral conditions by an SN 1 (P) mechanism for n= 1, 2, and 3 but an SN2 (P) or addition–elimination mechanism for n= 0; this is analogous to the classical SN1 vs. SN2 mechanisms observed reactions at tetrahedral carbon.
无环膦中,Ar Ñ P(OR)5- ñ与Ñ = 0-3由一个显示出在中性条件下水解小号Ñ 1(P)机构,用于Ñ = 1,2,和3,但一个小号Ñ 2(P )或加法消除机制,n = 0;这类似于在四面体碳上观察到的经典S N 1与S N 2机理。
