WebWe 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. WebThe catalyst also showed no significant loss of catalytic activity during the recycling process. ... in Studies in Surface Science and Catalysis, 2007. 3.4 Immobilization by impregnation and ion exchange. ... This is clear evidence that despite the loss of one chiral ligand due to the method of immobilisation, the spatial confinement leads to a ...
Webembodies the evolution of asymmetric catalysis, since it allows the recycling of the catalyst for several runs until degradation.

WebMay 13, 2002 · 1.. IntroductionAsymmetric homogeneous catalysis is a powerful tool for the efficient synthesis of enantiomerically enriched chiral compounds. 1 Application of this methodology on a wide scale is often prevented by issues relating to purification of the reaction products and recyclability of the precious chiral catalysts. The immobilization … WebJan 17, 2011 · Inherently chiral calixarenes, whose chirality is based on the absence of a planar symmetry or an inversion center in the molecules as a whole through the asymmetric array of several achiral groups upon the three-dimensional calix-skeletons, are challenging and attractive chiral molecules, because of their potential in supramolecular chemistry. …
WebDec 2, 2014 · An immobilized chiral bifunctional iminophosphorane superbase organocatalyst has been developed and applied in a range of challenging enantioselective reactions. A unique feature of this novel catalytic system is that the final step creation of the iminophosphorane occurs at the point of immobilization. The utility of the immobilized …
