aerobic oxidation of pyridine-based secondary alcohols. In this complex, a cobalt ion (the one in the middle, labeled Co2) has a novel trigonal-prismatic structure coordinated with six oxygen atoms from the substrate. The molecular oxygen present in air plays a major role in enabling this transformation to be catalytic. This aerobic catalytic reaction is very selective to pyridine-based secondary alcohols
成功地分离出了一种不寻常的三核钴配合物,并用Co(OAc)2 ·4H 2 O催化了吡啶基仲醇的好氧氧化反应。在这种络合物中,钴离子(中间的一个,标记为Co2)具有与底物上的六个氧原子配位的新型三角棱晶结构。空气中存在的分子氧在使这种转化具有催化作用方面起着重要作用。与基于伯醇的吡啶基仲醇相比,这种有氧催化反应具有很高的选择性。
