been prepared in order to investigate the steric effect in 1,2-migration reaction of rhodium(II) carbene. Through the investigation on the diazo decomposition of these compounds with Rh2(OAc)4, it was found that the steric effect could dramatically influence the migratory aptitude. In many cases, the steric effect could override the inherent electronic effect of the substituent.
为了研究铑(II)卡宾在1,2-迁移反应中的空间效应,已经制备了一系列带有不同取代基的重氮羰基化合物。通过对这些化合物与Rh 2(OAc)4的重氮分解研究,发现空间效应可显着影响迁移能力。在许多情况下,空间效应可能会取代取代基的固有电子效应。
