Continuous-flow microreactors and multidimensional on-line analytics for catalytic reaction kinetics studies under spatial confinement

We will study Mo-alkylidyne N-heterocyclic carbene (NHC) catalyzed, alkyne metathesis-based macrocyclization and (Z) selective Rh NHC-catalyzed hydrosilylation and hydroamination reactions of alkynes, all under confinement. The overarching idea in the use of these entirely different catalytic reactions is to develop a unifying concept for confinement effects in catalytic reactions with both large and small substrates. Reactions will be run in continuous-flow microreactors. An instrumental platform with on-line separation and detection will be established to quantify conversion and selectivity under the respective reaction conditions and to determine reaction kinetics rapidly and reproducibly.

Research focus in the 1st funding period (2018-2022):
Immobilized Molybdenum Imido, Tungsten Imido- and Tungsten Oxo Alkylidene N-Heterocyclic Carbene Complexes for Olefin Metathesis
