Benzyne is highly unstable. For example, in a molecule with an -ene and an -yne group, addition occurs preferentially at the -ene. Reactions specific for terminal alkynes[ edit ] In addition to undergoing the reactions characteristic of internal alkynes, terminal alkynes are reactive as weak acids, with pKa values 25 between that of ammonia 35 and ethanol They show greater tendency to polymerize or oligomerize than alkenes do.

General, Today,1 The hydration reaction gives an enol via the addition of one equivalent of water, a structure that tautomerizes to form a ketone or aldehyde. The "cycloadduct" derived from the addition of alkynes to 2-pyrone eliminates carbon dioxide to give the aromatic compound.
Synthesis benzils from easily accessible diarylacetylene derivatives. We used I 2-catalyzed potassium xanthate to synthesise dixanthogen, then diphenylacetylene and dixanthogen in the absence of EtOCS 2 K give the benzil product in 83% yield. Wang.

For the synthesis of diphenylacetylene the 3elting point was also close to the literature value, which reports a melting point of 61°C. The yield however was quite poor, only around half of the product was obtained implying.
