Abstract: Ahighly efficient Pd-BMImCl/TiOy-SiOx catalyst system synthesized through sol-gel method from palladium complex, ionic liquid, titanate and silicate esters was found for the oxidative carbonylation of amines. The catalyst efficiency was much higher than that reported in previous papers and the TOFnumber reached to 10372 when catalyst 0.05%Pd-4.6%BM ImCl/TiOy-SiOx was used. The usability of ionic liquid was the key point for preparation of this catalyst system because of its high dissolvability to palladium complex and affording appropriate micro-environment for the reaction. The synergism among palladium complex, ionic liquid, titanate and silicate was the main reason for the high catalytic activity of the catalyst system. BET, AESand XRDwere used to characterized the catalysts in detail.
