The selective synthesis of basic chemicals can also be achieved by relay catalysis, where the bifunctional catalysts consist of metal oxides (such as the solution solid ZnO-ZrO2, and the spinel structure of ZnCr2O4, ZnAl2O4) and zeolites (such as SAPO-34, ZSM-5, MOR). The activation of...
Relay catalysis at a boron centre The significance of chirality - the property of'handedness' - in nature cannot be understated. The characteristic is inherent in the molecules that define life, and in most of the biologically active, naturally occurring compounds that h... V Jeso,GC ...
relay catalysis.And in our opinion,the study of new catalysis systems will continue to be an exciting research area,the inquiry of the applications in the total synthesis of natural products is worthy of further investigation and the exploration of appropriate catalysis systems applied in industrial ...
We report a strategy that increases selectivity to urea using a hybrid catalyst: two classes of site independently stabilize the key intermediates needed in urea formation, *CO2NO2 and *COOHNH2, via a relay catalysis mechanism. A Faradaic efficiency of 75% at wastewater-level nitrate ...

Asymmetric metal/organo relay catalysis, utilizing a metal complex and a chiral organocatalyst in a one-pot cascade reaction, is aimed to sequentially impart activation on multiple steps by distinct catalysts. Such a catalysis merges the advantages of both metal catalysis and organocatalysis, providing...
