[reaction: see text] A highly selective catalytic reductive isomerization reaction is described. The extremely mild and neutral reaction conditions (10% Pd/C, H2, and MeOH at 0 degrees C) tolerate a wide range of functional groups and generally result in excellent yields. Mechanistic studies suggest that this reaction does not proceed via a stepwise reduction/elimination sequence or a pi-allylpalladium
[反应:见正文]描述了高度选择性的催化还原异构化反应。极其温和和中性的反应条件(0摄氏度下10%Pd / C,H2和MeOH)可耐受各种官能团,通常可产生出色的收率。机理研究表明,该反应不会通过逐步还原/消除顺序或π-烯丙基铝中间体进行。
