Catalytic Enantioselective Synthesis of Inherently Chiral Macrocycles by Dynamic Kinetic Resolution

Kinetically fast racemization of chiral substrates through an achiral intermediate and enantioselective functionalization of one of the enantiomeric substrates forms the basis of the dynamic kinetic resolution (DKR) of centrally chiral molecules. We report ...

Lignin Hydrogenolysis over Bimetallic Ni-Ru Nanoparticles Supported on SiO2@HPS

Lioubov Kiwi

Lignin obtained by hydrogenolysis of lignocellulose biomass is a prospective source of valuable green fuels and chemicals such as monophenols. One of the key factors in the chemical decomposition of lignin to monophenols is an efficient catalyst. Inert por ...

3D vs. turbostratic: controlling metal-organic framework dimensionality via N-heterocyclic carbene chemistry

Emad Oveisi, Wendy Lee Queen, Mounir Driss Mensi, Mehrdad Asgari, Shuliang Yang, Ilia Kochetygov, Vikram Vinayak Karve, Till Marian Schertenleib, Anita Justin

Using azolium-based ligands for the construction of metal-organic frameworks (MOFs) is a viable strategy to immobilize catalytically active N-heterocyclic carbenes (NHC) or NHC-derived species inside MOF pores. Thus, in the present work, a novel copper MOF ...

Development of Catalytic Asymmetric C-H Functionalizations with Chiral Cyclopentadienyl Iridium(III) Complexes

Yun-Suk Jang

Cp*Ir(III) catalyzed C-H functionalization is a growing field, since it provides novel complementary reactivities, but enantioselective C-H functionalization reactions with this metal remain a niche. This thesis investigates CpXIr(III) catalyzed asymmetric ...

Floating conductive catalytic nano-rafts at soft interfaces for hydrogen evolution

Hubert Girault, Micheal Diarmaid Scanlon

Mo2C nanowires and composites of Mo2C nanoparticles formed on multiwalled carbon nanotubes (Mo2C/CNT) were developed as advanced catalysts for hydrogen evolution at a polarised water–1,2-dichloroethane interface. Each catalyst acts as a catalytic nano-raft ...
