| 21. | Generally the substrate will be an alkene or alkyne.
|
| 22. | Azides and alkynes are other examples of chemical reporters.
|
| 23. | It is composed of both alkyne and alkene groups.
|
| 24. | Alkyne and benzyne derivatives of titanocene are well known.
|
| 25. | The molecule consists of phenyl groups attached to both ends of an alkyne.
|
| 26. | Hence, this reaction is more useful for terminal alkynes than internal alkynes.
|
| 27. | Hence, this reaction is more useful for terminal alkynes than internal alkynes.
|
| 28. | Homogeneous Catalytic Hydroamination of Alkynes and Allenes with Ammonia.
|
| 29. | Alkyne trimerisation of three 2-butyne ( dimethylacetylene ) molecules yields hexamethylbenzene.
|
| 30. | Upon addition of the alkyne a [ 2 + 2 ] cycloaddition occurs.
