mild and efficient method has been developed for the chemoselective preparation of 1,1-diacetates (acylals) from aldehydes catalyzed in the presence of a catalytic amount (0.1 mmol) of anhydrous cobalt(II) bromide under solvent-free conditions. The remarkable selectivity under mild and neutral conditions, excellent yields, short reaction time, and easily available and inexpensive catalyst are important
已开发出一种温和有效的方法,用于在无溶剂条件下,在催化量 (0.1 mmol) 无水溴化钴 (II) 存在下催化醛类化学选择性制备 1,1-二乙酸酯(酰基)。在温和和中性条件下显着的选择性、优异的收率、反应时间短以及易于获得且廉价的催化剂是该方法的重要特征。
