Nickel Complexes Immobilized in Modified Ionic Liquids Anchored in Structured Materials for Ethylene Oligomerization

Ionic Liquids for Advanced Materials

Multidisciplinary research has served as the cornerstone of the first year ILEAD MURI programs leading to working collaborations among scientists and engineers with graduate student exchanges, real-time feedback, and multidisciplinary peer-reviewed publications. The MURI research team is organized according to interdisciplinary and integrative fundamental questions of science and engineering, a...

Enantioselective allylation of aldehydes catalyzed by chiral indium(III) complexes immobilized in ionic liquids.

In the presence of chiral catalytic complexes prepared from In(OTf)3 and chiral PYBOX ligands, allytributylstannane reacted with aldehydes in ionic liquids to afford the corresponding homoallylic alcohols in high enantioselectivities (86-94% ee) and good yields (68-89%); the chiral catalysts immobilized in ionic liquids could be reused with comparable enantioselectivities and yields.

Ionic Liquids in Photopolymerizable Holographic Materials

Tolerance of Immobilized Yeast Cells in Imidazolium-Based Ionic Liquids

Ionic liquids (ILs) are considered as another ’green solvent’, after the supercritical carbon dioxide. They are a promising reaction medium for biocatalysis process. The tolerance of active cells in hydrophobic imidazolium-based ILs (1-R-3-methylimidazolium hexafluorophosphate, [RMim][PF6]) has been studied in this work. Calcium-alginate-entrapped baker’s yeast has been chosen as the model of l...

Nickel and Palladium Complexes with New Phosphinito - Imine Ligands and Their Application as Ethylene Oligomerization Catalysts

Phosphinito-imines, a new class of P,N donors, are readily generated by reaction of bulky arylamide anions [RCONAr] (R = Me or t-Bu; Ar = 2,6-i-Pr2C6H4) with chlorophosphines ClP(R)2. In solution, free phosphinito-imines exist in equilibrium with the corresponding amidophosphine tautomers, containing a nitrogen-bound P(R)2 group. However, reacting the tautomer mixtures with metal precursor comp...
