Recent 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 کاملPalladium Catalysts in Organic Synthesis
The main catalysts which are traditionally used for the hydrogenation of organic compounds are supported platinum group metals, and while these heterogeneous catalysts are generally not effective in carbon-carbon bond forming reactions, there has been a growing interest in recent years in soluble complexes of the platinum group metals for use as catalysts in organic synthesis. Rhodium catalysed...
متن کاملPolymer - bound osmium oxide catalysts ’
Polymer-supported oxidic osmium catalysts based on cross-linked poly(4-vinyl pyridine) were synthesized by various routes and characterized by a number of physical techniques (Raman, IR, XPS, “C and 15N solid-state NMR spectroscopy). Model compounds of type Os,O,L, (L = pyridine, 4-iso-propyl pyridine, and 4-tert-butyl pyridine) were obtained under the conditions of the catalyst synthesis. The ...
متن کاملOrganic Synthesis using Clay Catalysts
One of the major current challenges before chemists is to develop synthetic methods that are less polluting, i.e., to design clean or ‘green’ chemical transformations. The chemical manufacturing processes should be such that they do not cause permanent damage to the environment or disturb the ecological balance. Ways to minimize the consumption of energy and raw materials used in synthesis must...
متن کاملPorphyrins as Catalysts in Scalable Organic Reactions.
Catalysis is a topic of continuous interest since it was discovered in chemistry centuries ago. Aiming at the advance of reactions for efficient processes, a number of approaches have been developed over the last 180 years, and more recently, porphyrins occupy an important role in this field. Porphyrins and metalloporphyrins are fascinating compounds which are involved in a number of synthetic ...
