Indium(III) chloride efficiently catalyzes the protection of a variety of aldehydes and ketones to their corresponding 1,3-dioxolanes and dialkyl acetals in refluxing cyclohexane. On the other hand, deprotection of acetals is also achieved in refluxing aqueous methanol under the catalysis of indium(III) chloride.
氯化铟(III)在回流的环己烷中有效催化各种醛和酮对其相应的1,3-二氧戊环和二烷基缩醛的保护。另一方面,在氯化铟(III)的催化下,在回流的甲醇水溶液中也可以实现缩醛的脱保护。
