ABSTRACT We have systematically studied the reactions of acetalization and found that high reaction efficiency can be achieved using cheap and readily available organic Eosin Y as catalyst. The reaction proceeds smoothly under house bulbs and shows excellent functional group tolerance. The substrates of the reaction system are compatible with aromatic aldehydes, aliphatic aldehydes, aromatic ketones
摘要 我们系统地研究了缩醛化反应,发现使用廉价易得的有机曙红 Y 作为催化剂可以实现高反应效率。反应在室内灯泡下顺利进行,并显示出优异的官能团耐受性。该反应体系的底物与芳香醛、脂肪醛、芳香酮和环酮相容,收率高。图形概要
