摘要：

Zr(HSO4)(4)/SiO2 promotes the regio-, stereo- and chemoselective Claisen-Schmidt condensation of aromatic aldehydes with ketones under solvent-free conditions with improved yields. The work-up of the reaction Mixture is simple. and the Catalyst is easily removed from the products by simple filtration.
