Synthesis of Diarylethynes from Aryldiazonium Salts by Using Calcium Carbide as an Alkyne Source in a Deep Eutectic Solvent
An efficient method for the synthesis of diarylethynes from aryldiazonium salts by using calcium carbide as an alkyne source at room temperature in a deep eutectic solvent is described. The salient features of this protocol are an inexpensive and easy-to-handle alkyne source, a nonvolatile and recyclable solvent, mild conditions, and a simple workup procedure.

Nucleophilic displacement of fluorine from fluorodiarylacetylenes by alkoxide and phenoxide
Difluoroarylacetylenes synthesized in dimethylformamide in the presence of potassium tert-butoxide from fluorobenzyl-1H(or 2H)benzotriazoles and N-fluorophenylmethyleneanilines, undergo facile displacement of fluorine by tert-butoxide and phenoxide.

Diarylacetylenes, enamines and acetylenic polymers and their production
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.
