MgX to form the corresponding diol product, dehydrating the diol product to the corresponding dialkene; and hydrogenating the diol product to form the corresponding aniline. The 2,6 disubstituted anilines can be used to produce N-Heterocyciic Carbenes (NHCs). The NHCs can find application in various fields such as organic synthesis, catalysis and macromolecular chemistry. Palladium catalysts containing the NHCs are also described.
一种制备2,6-二取代苯胺的方法包括:将2-氨基异苯二甲酸二酯与足够的Grignard试剂R2CH2MgX反应以形成相应的二元醇产物,脱水二元醇产物以形成相应的双烯烃;并氢化二元醇产物以形成相应的苯胺。2,6-二取代苯胺可用于生产N-杂环卡宾(NHCs)。NHCs可在有机合成、催化和高分子化学等各个领域中找到应用。还描述了包含NHCs的钯催化剂。
