Difluoroarylacetylenes synthesized in dimethylformamide in the presence of potassium tert-butoxide from flourobenzyl-1H(or 2H)benzotriazoles and N-flourophenylmethyleneanilines, undergo facile displacement of flourine by tert-butoxide and phenoxide.

Diarylacetylenes and diarylenamines are synthesized from a Schiff's base and an N-arylmethylheterocycle; these compounds are useful as intermediates for a variety of polymers; in particular an efficient process is provided for producing diaryl acetylenes useful in the efficient production of acetylene group-containing polymers which can be cross-linked to produce high strength polymers free of structural defects such as conventionally arise as a result of liberation of volatiles during the cross-linking.
