Organocatalytic ring-opening polymerization.
Modern synthetic methods have revolutionized polymer chemistry through the development of new and powerful strategies for the controlled synthesis of complex polymer architectures.1-5 Many of these developments were spawned by new classes of transition metal catalysts for the synthesis of new polyolefin microstructures,5 the design of highly efficient families of “living” polymerization strateg...
متن کاملEnantioselective Ring-Opening
Ever since Nugent first reported a practical, catalytic method for the enantioselective opening of meso-epoxides with trimethylsilyl azide (TMSN3), [1] such desymmetrization reactions of epoxides and aziridines using a variety of nucleophiles have been the subject of extensive research. The less developed ring-opening reactions, those of meso-aziridines by carbon and nitrogen nucleophiles, give...
متن کاملSynthesis of Polysiloxanes In Microemulsion Via ring opening of D4
Polydimethylsiloxane (PDMS) has been synthesized by ring-opening polymerization of octamethylcyclotetrasiloxane (D4) in microemulsion with acidic catalyst. The structure and properties of microemulsion were characterized by Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FT-IR), Photo Correlation Spectroscopy (PCS). The effect of the variation in pH value, amoun...
متن کاملTandem Ring-Opening-Ring-Closing Metathesis for Functional Metathesis Catalysts.
Use of a tandem ring-opening-ring-closing metathesis (RORCM) strategy for the synthesis of functional metathesis catalysts is reported. Ring opening of 7-substituted norbornenes and subsequent ring-closing metathesis forming a thermodynamically stable 6-membered ring lead to a very efficient synthesis of new catalysts from commercially available Grubbs' catalysts. Hydroxy functionalized Grubbs'...
