Zirconium

The zirconium-catalyzed asymmetric carboalumination (ZACA) reaction, which was developed by Nobel laureate Ei-ichi Negishi, is perhaps one of the best-known examples of common applications of a zirconium catalyst. The ZACA reaction provides a means for chiral functionalization of alkenes with organoaluminum agents, catalyzed by a chiral bis(indenyl)zirconium catalyst. Recent studies have examined the efficiency of the ZACA reaction of other functional groups, such as: allylbenzenes, styrenes, diallyl(dimethyl)silanes, and 1,4-dienes.

Another notable zirconium catalyst is zirconium dioxide or zirconia. The list of applications of zirconia catalyst in heterogeneous catalysis is rapidly growing. Some of the applications include: decomposition of nitric oxide, reduction of carboxylic acid to aldehydes, selective dehydration of secondary alcohols to terminal alkenes, and hydrogenation of carbon monoxide to isobutane.

Sigma-Aldrich is proud to present a vast selection of zirconium catalysts to meet your chemical synthesis needs.
