Porous metal-organic frameworks of Zr clusters connected by organic linkers 1,4-benzenedicarboxylic (UiO-66) and biphenyl-4,4-dicarboxylic (UiO-67) were synthesized using a solvothermal method, and used as efficient heterogenous catalysts for acetalization of aldehydes and alcohols. The catalysts we...
