Primary hydroxylamines, RNHOH, decompose readily in the presence of transition metal ions. We show that this reactivity can be arrested by ligand design via an intramolecular hydrogen bond. Six metal complexes with an intact NHOH group were synthesized and crystallographically characterized. The Cu–hydroxylamine complexes can catalyze the aerobic oxidation of benzylic alcohols.

Salen型金属配合物中伯羟胺的分子内H键稳定

伯羟胺,RNHOH,在过渡金属离子的存在下很容易分解。我们表明可以通过分子内氢键通过配体设计来阻止这种反应性。合成了六种具有完整 NHOH 基团的金属配合物并对其进行了晶体学表征。Cu-羟胺配合物可以催化苯甲醇的有氧氧化。
