| titleOfInvention | Method for making ethynylated aromatic compounds |
| abstract | 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. |
