| 摘 要： | 本文简要叙述了由立体电子效应控制的频哪醇重排反应。指出在频哪醇重排反应中,离去基团和迁移基团总是处在反式共平面位置,而迁移基团与它所在碳上的羟基氧上一对孤电子也处于反式共平面位置。在这对孤电子的立体电子效应作用下,促使重排基团带着一对电子从离去基团的反位上进行1,2——位移。

| Abstract: | The pinacol rearrangements controlled by stereoelectronic effect are briefly discussed. The characteristics of the reaction are that the learning group and the migrating group lie trans to each other and so are the migrating group and a pair of unshared electrons on oxygen of hydroxy on the carbon bonded with the migrating group. By the action of the stereoelectronic effect of this pair of unshared electrons, the migrating group with its a pair of bonding elections undergoes a 1,2-shift from the opposite position of the learing group. |
