| 11. | The carbopalladation step is regioselective when unsymmetrical alkynes are used.
|
| 12. | For example, they undergo Diels-Alder reactions with electrophilic alkynes.
|
| 13. | The selectivity of the hydrozirconation of alkynes has been studied in detail.

| 15. | Alkynes form many compounds with upon reaction with iron carbonyls.
|
| 16. | Cyclooctatetraene is produced from acetylene via the intermediacy of metal alkyne complexes.
|
| 17. | Via the Fritsch Buttenberg Wiechell rearrangement, alkynes are prepared from vinyl bromides.
|
| 18. | The most commonly used dipolarophiles are alkenes and alkynes.
|
| 19. | These include cyclophanes, Platonic hydrocarbons, pyramidal alkenes, and cyclic alkynes.
|
| 20. | Some alkynes undergo amination in the presence of gold ( III ) catalysts.
