Research Interests
While commonly nature is considered a source of
inspiration for chemists, organometallic and coordination chemistry
provide a divers set of functions, which can be used to probe, augment
and improve nature. Prof. Eppinger's research group combines homogeneous
catalysis and synthetic biology to establish new catalysts for novel
chemistry. Introducing tools and concepts of synthetic chemistry into
living cells opens an unexplored research area, which integrates
molecular catalysis' versatility and biocatalytic selectivity. Tailoring
the interactions of molecular catalysts with biological ligands results
in novel selectivities and reactivities. The four currently active
research projects connect the interface of organometallic chemistry,
molecular/microbiology and catalysis:
development of organometallic catalyst motifs,
which are stable and active under physiological conditions. The design
of catalysts motifs, which exhibit high activity at room temperature in
water targets Green Chemistry applications and is a prerequisite for
the synthesis of artificial metalloenzymes.
development tailored artificial metal centers in host-proteins.
Integrating the specific advantages of organometallic catalysis and
enzymes, these systems target in selective hydrogenations,
cycloadditions, (amino)hydroxylations, C-H activation and cross–coupling
reactions.
Discovery of novel organometallic mechanism in enzyme catalysis.
This project targets to identify and characterize novel metalloproteins
and to improve the knowledge about how a protein framework augments
properties of metal centers. Characterization of iron sulfur cluster
enzymes with organometallic intermediates and extremophilic Red Sea
metalloenzymes are a current focus.
in vivo applications of metalloproteins and metal complexes.
In an industry sponsored project we investigate artificial
photosynthesis based on the combination of electrocatalytic CO2
reduction and microbial metabolism. Through collaborations, we have also
reactivated biomedical projects and are currently exploring in vivo
applications of the plethora of metal complexes available in our group.
This includes cytotoxicity studies as well as the design of
chemiluminescent metal complexes for cancer diagnostic.

protein serves as the penultimate enzyme of the recently discovered
non-mevalonate pathway for the biosynthesis of the universal isoprenoid
precursors, isopentenyl diphosphate and dimethylallyl diphosphate. The
enzyme catalyzes the reductive ring opening of 2C-methyl-d-erythritol
2,4-cyclodiphosphate, which affords 1-hydroxy-2-methyl-2-(E)-butenyl
4-diphosphate. The protein was crystallized...more
The
reaction of (S)-2,5-dihydrophenylalanine 1 with ruthenium(III) chloride
yields the μ-chloro-bridged dimeric η6-phenylalanine ethyl ester
complex 3, which can be converted into the monomeric analogue,
η6:κ1-phenylalanine ethyl ester complex 12, under basic conditions.
Studies were carried out to determine the stability and reactivity of
complexes bearing η6- and η6:κ1-chelating phenylalanine...more

carried out using the palladacycle,
[{Pd(μ-Cl){κ2-P,C-P(iPr)2(OC6H3-2-Ph)}}2] as pre-catalyst with different
bases and palladium concentrations. The highly active pre-catalyst

Rh(III) and Ir(III) Cp* complexes with pendant primary amine tether
were synthesized from a Cp*–NH2 tautomer and the respective metal(III)
chlorides. The electrophilic metal center and the nucleophilic side
chain functionality may be addressed separately under the appropriate
reaction conditions.
