The aminopropylated Silica-Gel hydrochloride (APSG.HCl) proved to be an efficient catalyst for the rapid conversion of carbonyl compounds in the corresponding acetals with high yields and in mild and selective conditions. In addition to the obvious advantages offered by heterogeneous catalysis, the present method results very useful when the presence of a weakly-acidic function chemically bonded on
氨基丙基化的二氧化硅-凝胶盐酸盐(APSG.HCl)被证明是在相应的缩醛中以高收率和温和选择性条件快速转化羰基化合物的有效催化剂。除了非均相催化提供的明显优点外,当在催化剂表面化学键合弱酸性官能团(烷基铵盐)时,本方法的结果也非常有用。是必需的(含有在酸性介质中不稳定的功能的化合物)。
