ABSTRACT
A center radially fibrous silica encapsulated TS-1 zeolite (TS-1@KCC-1) has been synthesized in a microemulsion system for the first time. Supporting the Rh(OH)3 species, this novel core-shell structured material serves as a robust bifunctional catalyst for one-pot synthesis of benzamide from benzaldehyde, ammonia and hydrogen peroxide, in which the aldehyde ammoximation and oxime rearrangement occur in a tandem way.
