| 41. | Alkyne trimerisation of dimethylacetylene also yields hexamethylbenzene in the presence of a suitable catalyst.
|
| 42. | In some complexes, the alkyne is classified as a four-electron donor.
|
| 43. | Metal-alkyne complexes are intermediates in the metal-catalyzed trimerization and tetramerizations.
|
| 44. | The monomers used in this polymerization are oligopeptides with terminal azide and terminal alkyne groups
|
| 45. | The hydroboration of alkynes gives vinylic boranes which oxidize to the corresponding aldehyde or ketone.
|
| 46. | They also demonstrate higher reactivity toward alkynes.
|
| 47. | Disilenes have Si = Si double bonds and disilynes are silicon analogues of an alkyne.
|
| 48. | "' Phenylacetylene "'is an alkyne hydrocarbon containing a phenyl group.
|
| 49. | Formal [ 2 + 2 + 2 ] cycloadditions also take place in alkyne trimerisation.
