Engineering novel tandem reactions using organometallic catalysts and metalloenzymes
Organometallic chemistry and bioinorganic chemistry are two prominent sub-disciplines of chemistry. Complexes of the transition metals are prominent components of both disciplines. On the one hand, considerable efforts in transition-metal catalysis have culminated in practical and efficient …

Engineering novel tandem reactions using organometallic catalysts and (metallo)enzymes
… synthesis is founded on three pillars: organometallic catalysis, organoca-talysis and biocatalysis. Over the years, catalysts of these three classes have enabled ground-breaking chemical transformations. The application of chemocatalysis to the manufacturing of chemicals is widespread, …

Supporting Well-Defined Platinum Group Metals in Metal-Organic Frameworks for Heterogeneous Catalysis
… highly selective transformations, homogeneous catalysts are paramount. The effectiveness of molecular organometallic catalysts in particular can be largely attributed to the precise tools available for synthesis and characterization of the ligands and metal complexes, which allow for fine …

Guanidinium Compounds: Synthesis, Oxoanion Binding, and Cellular Delivery
… guanidines are inspired by axially constrained organometallic catalyst ligands and have applications in oxoanion binding as dications and organometallic catalysts as dianions. I detail initial forays into determining the binding affinities of the guanidines to oxoanions through NMR titration …

Continuous separation and recycle of homogeneous catalysts in small scale flow system
The development of organometallic catalysts with high activity and selectivity has transformed the way both bulk and fine chemicals are produced. When such catalysts are applied in fine chemicals production, the presence of toxic heavy metals in these catalysts (Pd, Pt, Ru, Rh, etc.) can pose …

Synthesis of Functionalized Sustainable Polyesters via Controlled Ring-opening Polymerization of O-carboxyanhydrides
Despite the degradability and biocompatibility of poly(α-hydroxy acids), their utility remains limited because their thermal and mechanical properties are inferior to those of commodity polyolefins, which can be attributed to the lack of side-chain functionality on the polyester backbone. Attempts …
