摘要：

At least two possible pathways were found for the Beckmann rearrangement of acetophenone oxime to acetanilide over zeolite catalysts. In the first step, the N atom of the oxime is protonated over the Brønsted acid sites of an aluminum siliceous zeolite (see picture), but not over the silanol groups of a pure siliceous zeolite.
