The application of cyclic diaryliodonium salts in the synthesis of bioactive naturalproduct analogues was demonstrated. Axially chiral biaryls were obtained via the enantioselective ring opening of cyclic diaryliodonium salts. Regioselective borylation was key in accessing both enantiomers of a biphenol key intermediate in eight steps overall. 8,8″-Amino biflavones were synthesized, their bioactivity

Polyphenylene ether (PPE) compositions with good fire and flame retardant characteristics utilize lower levels of organophosphate fire-retardant, and therefore do not suffer from the drawbacks of previously known fire- and flame-retardant PPE compositions. The compositions include (a) a polymer component containing a polyphenylene ether; (b) glass or carbon reinforcing fibers in an amount sufficient to increase the modulus and strength of the polymer component; (c) a fire retardant component which is preferably an organophosphate fire retardant; (d) a mineral component in an amount effective to enhance the flame-retardant characteristics of the composition. Other conventional additives utilized in formulation of PPE may be included. The composition is made by mixing the ingredients and compounding into a composition which is suitable for injection molding. This composition can be used in the manufacture of injection molded articles such as electronic components, including television internals such as deflection yokes; printer chassis and plastic pallets.
