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.
