Conclusions
-
1.
By the replacement of carbonyl oxygen in ar-hydroxy-acetophenones and -biacetophenones by chlorine and treatment of the chlorides formed with sodamide, mono- and di-acetylenic phenols were obtained.
-
2.
By the oxidative polycondensation of a diethynylbiphenol dibenzoate a polymer was prepared which contained both diacetylenic chains and benzoyloxy groups.
-
3.
O-Ethynylphenols are much more stable than their para isomers and do not undergo oxidative condensation. The corresponding dimers were prepared via the benzoyl derivatives.
