| 31. | It is a hydrocarbon and the simplest alkyne.
|
| 32. | Terminal alkynes, including acetylene itself, can react with water to give aldehydes.
|
| 33. | Alkynes react similarly, forming the tetrahalo compounds.
|
| 34. | In carbo-benzene the ring bonds are extended with alkyne and allene groups.
|
| 35. | They also arise via carbonylation of alkynes and alkenes in the presence of thiols.
|
| 36. | This compound reacts with 3-hexyne in an alkyne trimerization to the benzocarborane.
|
| 37. | Palladium can also promote a radical addition of tin hydride to alkynes or alkenes.
|
| 38. | Alkyne protons by contrast resonate at high field in a 2 3 ppm range.
|
| 39. | The diene is known to react with amines, aldehydes, alkenes and alkynes.
|
| 40. | Also, what is the name for alkyne groups conjugated with a carbonyl system?
