Can sodium (just sodium, not with liquid ammonia) react with terminal alkynes in a simple acid-base reaction to form sodium alkynide and dihydrogen (just as it reacts with $\ce{H2O}$ to form sodium hydroxide and $\ce{H2}$)?

    $\begingroup$ "University Chemistry, Volume 2" by C. Parameshwara Murthy, p 164 says it can. No conditions are listed, though. $\endgroup$ – SendersReagent Feb 13 '16 at 14:21
  • $\begingroup$ @DGS- but that is in the presence of liq NH3 ,which would react with sodium to form NaNH2. The terminal alkyne then reacts with NaNH2 to liberate H2. I want to know if sodium can directly react with the alkyne $\endgroup$ – Surya Teja Feb 13 '16 at 15:17
  • $\begingroup$ I guess you may find your proof sooner or later, but you should understand that as sodium is solid and ethyn gaseous, there's not much point in reacting them like this. $\endgroup$ – Mithoron Feb 13 '16 at 16:11
  • $\begingroup$ Take a liquid alkyne. Also since they are mildly acidic, the metal must get solvated $\endgroup$ – Surya Teja Feb 13 '16 at 16:24

    $\begingroup$ The one I saw didn't mention ammonia, which is kind of crucial to that reaction if that is the mechanism. I'm assuming it wasn't there. $\endgroup$ – SendersReagent Feb 16 '16 at 9:06
