A simple and efficient chemoselective thioacetalization of carbonyl compounds has been achieved using Ce(OTf)3 (10 mol-%) as a catalyst under solvent-free conditions. Advantages of the methodology include very short reaction times, excellent yields, the catalytic use of a water tolerant Lewis acid, and simple recovery and reuse of the catalyst.
在无溶剂条件下,使用Ce(OTf)3(10 mol%)作为催化剂,已经实现了羰基化合物的简单有效的化学选择性硫缩醛缩醛化反应。该方法的优点包括非常短的反应时间,优异的产率,耐水路易斯酸的催化使用以及催化剂的简单回收和再利用。
