More Fluorous Isotope Chemistry
Right on the heels of our September 2010 Technical Newsletter that highlighted the use of fluorous techniques in isotope chemistry comes a US Patent Application from GE Healthcare claiming the use of perfluoro-aryliodonium salts for the preparation of 18F aromatics. … Continue reading
Fluorescent Fluorous Emulsions
An interesting Early View paper in Angewandte Chemie from the Swager group at MIT describes the fluorous biphasic synthesis of fluorescent poly(p-phenyleneethynylene)s (PPE’s). Highly conjugated polymers such as PPE’s have interesting fluorescence characteristics and the authors believed that the addition … Continue reading
Parallel Synthesis of O-aryloxyamines
Aryloxyamines are an interesting class of compounds which have been used in a variety of applications. They are excellent intermediates for the synthesis of a number of biologically active heterocycles. They also readily form very stable oximes and have therefore … Continue reading
Fluorous Crown Ethers
Phase transfer catalysis (PTC) has been an active area of interest for over 50 years and have now been incorporated into hundreds of industrial processes. The primary role of these catalysts are to transfer an inorganic reagent from a non-organic … Continue reading
