Halogenoacetylenes are probably one of the most intriguing classes of acetylene compounds. Although some synthetic routes to 1-haloacetylenes have been reported, there are very few reports on the syntheses of 1-fluoroacetylenes.[1] In 1959, the first synthesis of 1-fluoroacetylene itself was accomplished by Middleton and Sharkey, who used pyrolysis of fluoromaleic anhydride.[2] Five years later Viehe and et al. reported the synthesis of tert- ...
