He, Jian published the artcileZrOCl2 as a bifunctional and in situ precursor material for catalytic hydrogen transfer of bio-based carboxides, Application In Synthesis of 539-88-8, the main research area is zirconium oxychloride carboxide catalytic hydrogen transfer.
Herein, we for the first time describe a direct and effective catalytic system based on ZrOCl2·8H2O capable of facilitating the one-pot one-step tandem synthesis of GVL from bio-based furfural or furfuryl alc. in 2-propanol by integrating sequential transfer hydrogenation, ring-opening, and transfer hydrogenation-cyclization reactions. A maximum GVL yield of 63.3% and 52.1% was achieved from furfuryl alc. and furfural at 200°C, resp. The synergistic effect of [ZrO(OH)2]n·xH2O species and Bronsted acid species H+, derived from in situ hydrolysis of ZrOCl2·8H2O, is accountable for its remarkable catalytic performance. Moreover, calcination of the leftover solid after tandem synthesis of GVL could fabricate a hollow microrod ZrO2 material, in which the formation of a microrod morphol. and hollow structure was probably attributed to the electrostatic repulsion forces among particles in the alc. solution and removal of generated humins/coke during the reactions within collected solids via calcination, resp. Importantly, hollow microrod ZrO2 innovatively featuring a high BET surface area, a large amount of acid-base sites and facile active-site accessibility thereby exhibited a superior performance in the catalytic transfer hydrogenation of biomass-derived aldehydes or ketones to ZrO2 prepared by the precipitation method.
