在没有分子氧的情况下，在紫外光照射（>340 nm）下，各种芳香酮（例如苯乙酮衍生物和二芳基酮）在多晶二氧化钛（Degussa P25）上进行光催化氢化。通过选择乙醇作为牺牲空穴清除剂，将其氧化成乙醛，以优异的化学效率获得了所需的仲醇（10个例子的收率几乎为100%）。 (C) 2010 Elsevier B.V. 保留所有权利。
In the absence of molecular oxygen, various aromatic ketones such as acetophenone derivatives and diaryl ketones were photocatalytically hydrogenated on polycrystalline titanium dioxide (Degussa P25) under UV light irradiation (>340 nm). The desired secondary alcohols were obtained with excellent chemical efficiency (almost 100% yields for 10 examples) by choosing ethanol as a sacrificial hole scavenger, which was oxidized into acetaldehyde.
