    摘要: A method is disclosed for making amino-substituted ethynlated biphenyl compounds, which includes selectively nitrating symmetrically substituted biphenyl compounds, reacting the resulting nitro-substituted aromatic compound with a copper acetylide to replace the iodo substituents with ethynyl groups, and then reacting the ethynylated, nitro-substituted aromatic compound with hydrogen in the gas phase to reduce the nitro groups to amino groups. The preferred nitrating agent is nitronium trifluoromethanesulfonate, made by reaction of anhydrous nitric acid with trifluoromethanesulfonic anhydride in an anhydrous solvent.

    摘要: Novel processes are provided for synthesizing 2,2-bis(4-fluorophenyl)hexafluoropropane and the use of this synthesized monomer in polymerization reactions to form poly(arylethers) and poly(arylthioethers). Synthesis of 2,2-bis(4-fluorophenyl)hexafluoropropane involves converting the commonly available compound Bisphenol AF to an amino-substituted form, followed by treatment with borofluoric acid and a nitrite, and then an aromatic solvent to obtain the monomer. The monomer can be mixed with either a dihydroxy diphenyl hexafluoropropane or a dimercapto diphenyl hexafluorpropane to cause a nucleophilic substitution reaction, thereby yielding the desired poly(arylether) or poly(arylthioether).

    摘要: There are disclosed diethynylated diphenyl hexafluoropropane compounds, which are suitable for forming copolymers and carbon-carbon composites. These compounds are prepared in high yields by first providing a dihalogenated diphenyl hexafluoropropane compound, coupling the dihalogenated compound with ethynyltrimethylsilane in the presence of an organometallic catalyst to form a silylated ethynyl terminated diphenyl substituted compound and subsequently desilylating the compound to form the desired diethynylated diphenyl hexafluoropropane compound.
