摘要

A novel catalyst consisting of a Schiff base-copper complex on surface-modified silica-coated ferrite nanoparticles was been prepared and used for oxidative C-O cross-coupling reactions of 1,3-dicarbonyl compounds with formamides for the synthesis of enol carbamates. The new catalyst has also been used for esterification of alkylbenzenes with cyclic ethers.
