Synthesis of Derivatives of Alpha, Omega Difunctional PerfluoroaliphaticCompounds for Low Dielectric Constant Resins

摘要

Copper coupling reactions of perfluoroalkyl iodides with certain aryl iodideshave been studied. Simple trial tests were carried out between perfluorooctyl iodide and idobenzene and between perfluorohexyl iodide and 4-odophenol. The desired product were obtained in good yield. However, the coupling of 1,6-diiodoperfluorohexane and 4-iodophenol gave a product which could not be isolated or purified. Protection of the phenolic OH by methylation or acetylation gave the coupled alpha, omega products in good yield. copper coupling, fluoropolymer perfluoroalkyl phenols, fluoromonomers.
