acetate were hydrogenated selectively into the corresponding nitriles by using a recyclable catalyst, which consists of palladium nanoparticles entrapped in aluminum oxyhydroxide, Pd/AlO(OH) matrix. The reactions were conducted at room temperature and one atmosphere H2 pressure. Under identical reaction conditions just by changing solvent, reaction time and increasing catalyst amount the substrate α,
使用可回收催化剂将α , β-不饱和腈的乙酸乙酯溶液选择性氢化成相应的腈,该催化剂由包埋在羟基氧化铝 Pd/AlO(OH) 基质中的钯纳米颗粒组成。反应在室温和1个大气压的H 2压力下进行。在相同的反应条件下,仅通过改变溶剂、反应时间和增加催化剂用量,底物α , β-不饱和腈选择性地转化为叔胺。该催化剂可以重复使用至少五次,而不影响活性和选择性。该方法的适用性已被证明适用于各种α , β-不饱和腈。
