EXTENDED APPLICATION OF BALANCED IRON HYDRIDE/IRON BORON SYSTEM ON EFFICIENT AND SELECTIVE OLEFIN ISOMERIZATION AND BORYLATION AND NICKEL PROMOTED POLYETHYLENE UPCYCLING WITH GREEN HOUSE GAS AS FEEDSTOCK

Abstract

In section 1, we have reported a remote iron-catalyzed remote alkene borylation method via controlling the balance of iron-hydride and iron-boron species, and expanded the strategy application to chain walking, alkene di-functionalization and remote site selective borylation. For the substrates with a very remote double bonds shift, we have made a slight modification to gain a better result. Also, we have established a bioactive drug molecular by applying this strategy on the core intermediate synthesis, and investigated the mechanism via XAFS, EPR and deuterium labelling studies. In section 2, we have reported a nickel catalyzed carboxylation on polyethylene method, which owns the potential to build a new series of hydrogen gels that could be used in pharmaceutical and wastewater treatment fields. Under the optimized conditions of previous study, we have established an indirect strategy to introduce carboxyl groups on the polyethylene. And we have made preliminary test on upscaling the reaction by flow chemistry.
