Stagel, K., Pálvölgyi, Á. M., Delmas, C., Schnürch, M., & Schröder, K. (2023). Supported Ionic Liquid Phase (SILP) Allylic Alkylation of Amines in Continuous Flow. ChemCatChem, Article e202300381. https://doi.org/10.1002/cctc.202300381
We present the use of Pd-complex-containing supported ionic liquid phases (SILPs) as a novel approach for continuous-flow allylic alkylation of N-nucleophiles. This immobilization strategy gave simple access to air-tolerating catalyst frameworks, providing rapid and convenient access to various achiral and chiral N-allylation products. Under optimized conditions, the flow-reaction could be maintained for 3.5 hours with constant product output; meanwhile, only a marginal 0.7 wt % of ionic liquid leaching and no detectable palladium-complex leaching could be observed.
