متن کاملSoxhlet-dialysis: a method to recover soluble polymer supported catalysts{
There is a widespread interest in developing methods to recover homogeneous catalysts, particularly chiral catalysts, from a reaction mixture. The impetus to recover and reuse homogeneous catalysts stems not only from an economic standpoint but also from the need to eliminate contamination of the transition metal catalyst in the product and in the waste streams. The challenge is to recover the ...
متن کاملGraphitic Carbon Nitride Supported Catalysts for Polymer Electrolyte Fuel Cells
Graphitic carbon nitrides are investigated for developing highly durable Pt electrocatalyst supports for polymer electrolyte fuel cells (PEFCs). Three different graphitic carbon nitride materials were synthesized with the aim to address the effect of crystallinity, porosity, and composition on the catalyst support properties: polymeric carbon nitride (gCNM), poly(triazine) imide carbon nitride ...
متن کاملRecent applications of polymer supported organometallic catalysts in organic synthesis.
Recent developments concerning the application of polymer supported organometallic reagents in solid phase synthesis are reviewed, with a special focus on methodology for carbon-carbon formation. Examples of reactions that are covered include the classical Suzuki, Sonogashira and Heck coupings, but also aryl amination, epoxide opening, rearrangements, metathesis and cyclopropanation. Applicatio...
متن کاملPolymer-Supported Raney Nickel Catalysts for Sustainable Reduction Reactions.
Green is the future of chemistry. Catalysts with high selectivity are the key to green chemistry. Polymer-supported Raney catalysts have been found to have outstanding performance in the clean preparation of some chemicals. For example, a polyamide 6-supported Raney nickel catalyst provided a 100.0% conversion of n-butyraldehyde without producing any detectable n-butyl ether, the main byproduct...
