organocatalyst at room temperature in high yields and excellent selectivity. It also shows the potential to selectively benzoylate primary alcoholic groups of aminoarylalkanols and primary-secondary diols as well as primary amino group of alkyl amines in the presence of aryl amines under similar conditions. A rationale for the selectivity and efficiency of the reaction has been provided.
在室温下,当2-10 mol%的PMDETA有机催化剂存在时,三氯甲基苯基酮苯甲酸酯化还含有酚基的化合物中的伯和仲脂肪醇基团,具有很高的收率和优异的选择性。它也显示了在类似条件下在芳基胺存在下选择性地苯甲酰化氨基芳基链烷醇和伯-仲二醇的伯醇基以及烷基胺的伯氨基的潜力。已经提供了反应的选择性和效率的原理。
