Abstract
Imidazolium salts bearing TEMPO groups react with commercially available copper powder affording Cu-NHC complexes. The in situ generated Cu-NHC-TEMPO complexes are quite efficient catalysts for aerobic oxidation of primary alcohols into aldehydes. The catalyst is easily available, and various primary alcohols were selectively converted to aldehydes in excellent yields.
摘要
含三氮唑基团的离子液体与市售的铜粉反应生成 Cu-NHC 配合物。原位生成的 Cu-NHC-TEMPO 配合物是一种高效的催化剂，可用于伯醇的有氧氧化为醛。该催化剂易得，各种伯醇都以优异的收率选择性转化为醛。
