ABSTRACT:
Bis(ethynylphenyl) compounds are prepared by an improved synthesis process which increases yield and is suitable for large scale synthesis operations. Aromatic dianilines are diazotized to form aromatic halides that are subsequently coupled with an end-protecting group having acetylenic moieties. The end-protecting groups are subsequently removed leaving the desired diethynyl derivative in quantitative yields.
