A saltlike compound formed from acetylene and a metal, containing the anion (C≡C)– or HC≡C–. Acetylides are typically unstable or explosive.
- ‘The acetylides should be carefully mixed with the raw aluminum nitride.’
- ‘Apart from being deactivated, potentially explosive acetylides are also produced.’
- ‘Excess acetylene should be vented from reaction flasks, tubing, etc., rather than scrubbed with strong base to avoid the formation of acetylides.’
- ‘The acetylides of silver, copper, mercury, and gold are detonated by heat, friction, or shock.’
- ‘The acetylides are also strong bases and in reactions with secondary or tertiary alkyl halides elimination reactions can occur instead.’
