Aerobic waste-minimized Pd-catalysed C–H alkenylation in GVL using a tube-in-tube heterogeneous flow reactor

Abstract

Herein we report the design and application of the first tube-in-tube packed-bed flow reactor for the development of a heterogeneous palladium catalysed oxidative C–C bond formation process. In particular, we...

A generalized kinetic model for compartmentalization of organometallic catalysis

“…Indeed, a recent experimental demonstration of compartmentalized Fujiwara–Moritani reaction with a “tube-in-tube” design is consistent with our model's prediction. 61 As the minimally permeable tube-in-tube reactor is estimated to possess F V ∼ 10 −28 s −1 that well surpasses the criterion F V ≪ k 2 ( vide supra ), our model predicts little catalyst deactivation and high reaction efficiency ( γ ∼ 1 and R I ∼ 10 31 s −1 ). Indeed, our predictions are consistent with the experimental observations 61 and illustrate the utility of our model.…”

Synthesis of Pd–AuAg trimetal nanohybrids with controlled heterostructures and their application in the continuous flow catalytic reduction of Cr(vi)

“…Conducting heterogeneous catalysis in continuous ow reactors offers several benets, including low consumption of reagents and catalysts (which reduces waste production and promotes environmental friendliness), ease of handling reactants, continuous product formation, reusability of catalysts, and the ability to perform reactions under harsh conditions. [44][45][46][47][48][49][50] In addition, scale-up is straightforward and the potential for chemical accidents such as leaks, res, and explosions is relatively low. [51][52][53] Intuitively, combining the concepts of catalytic heavy-metal ion conversion in water and continuous ow chemistry could provide an ideal strategy for treating heavymetal ions in wastewater because it can promote cleaner, safer, and continuously scalable ow methodologies in a sustainable manner for water purication.…”
