Continuous-flow microreactors and multidimensional on-line analytics for catalytic reaction kinetics studies under spatial confinement (B02)

• Subject Area: Preparatory and Physical Chemistry of Polymers ; Inorganic Molecular Chemistry - Synthesis and Characterisation ; Organic Molecular Chemistry - Synthesis and Characterisation
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 358283783

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.
