The stereochemistry of the various conversions in the 1,2-diphenyl-1-propyl system was measured as a function of aromatic substituent. For β-anisyl groups the reaction occurred with retention of configuration. For compounds with indifferent electron donating aryl groups, the conversions were stereoselective forming mostly threo product. For β-p-nitrophenyl groups the stereochemical course of the reaction
测量 1,2-二苯基-1-丙基系统中各种转化的立体化学作为芳族取代基的函数。对于 β-茴香基,反应发生时保留构型。对于具有不同给电子芳基的化合物,转化是立体选择性的,主要形成苏式产物。对于 β-对硝基苯基,反应的立体化学过程是“外消旋化”。后一反应与开放离子的存在有关。在某些反应中,无论取代基如何,都会以低产率形成乙酸盐产物,并保留构型。乙醇分解的动力学与苏式异构体的(部分)桥连离子形成和赤式物质的广泛开放离子形成一致。
