A process for the preparation of an amide of the formula
wherein R is an eventually substituted alkyl, alkenyl, aralkyl or phenyl group, by hydrolysis of a nitrile of the formula (II)
wherein R is as defined above, in the presence of a base and hydrogen peroxide using an organic quaternary ammonium salt and/or a tertiary amine as a catalyst. This process is useful for the preparation of amides of formula (III)
wherein n is 1, 2 or 3
Ar and Ar' are eventually substituted phenyl groups
R3 is hydrogen or a substituent.
These amides can be decomposed in amines by a halogen or a hypohalite in the presence of a base.
一种通过水解式(II)腈制备式(I)酰胺的工艺
其中 R 是最终取代的烷基、烯基、芳基或苯基,通过水解式(II)的腈
其中 R 如上定义,在碱和过氧化氢存在下,使用有机季铵盐和/或叔胺作为催化剂。该工艺可用于制备式 (III) 的酰胺
其中 n 为 1、2 或 3
Ar 和 Ar'为最终取代的苯基
R3 是氢或取代基。
这些酰胺可以在碱存在下通过卤素或次卤素分解成胺。
