1,3-Cyclohexadiene hydrogenation in the presence of a palladium-containing catalytic system based on an MOF-5/calixarene composite

A palladium-containing material based on the new metal-organic framework structure MOF-5/20% calix[4]arene have been synthesized and characterized by physical and chemical methods for the first time. The catalytic activity of the 3% Pd/MOF-5/20% calix[4]arene composite in partial 1,3-cyclohexadiene hydrogenation into cyclohexene is fairly high and is comparable with that of the 5% Pd/C reference catalyst.
