Catalytic activity of CuBTC and FeBTC was investigated in Beckmann rearrangement of a series of aromatic and non-aromatic oximes and compared with that of zeolites Beta and USY. The reactivity of substrates in Beckmann rearrangement increases in the order camphor oxime < cyclohexanone oxime < indanone oxime < acetophenone oxime. While zeolites show higher activity in the transformation of relatively
在一系列芳香族和非芳香族肟的贝克曼重排中研究了CuBTC和FeBTC的催化活性,并将其与Beta和USY沸石进行了比较。贝克曼重排中底物的反应性按樟脑肟<环己酮肟<茚满酮肟<苯乙酮肟>的顺序增加。沸石在相对较小的芳族化合物(乙酰苯肟,茚满酮肟)和非芳族肟(环己酮肟)的转化中显示出更高的活性,在所有反应中均对目标内酰胺具有100%的选择性,而CuBTC在大体积肟的转化中活性最高。 。据推断,与Beta和USY沸石相比,CuBTC的质地偏爱可能是其促进笨重的樟脑肟转化的原因。
