SUMMARY

Alkynes can react with ketones when treated with sodium amide (NaNH2), which facilitates the alkyne's nucleophilic behavior. The discussion highlights a specific reaction involving tetraphenylcyclopentadiene and diphenylacetylene, conducted under heat in silicone oil. This method does not utilize any bases, indicating a unique approach to the reaction process. Understanding this reaction mechanism is crucial for organic chemistry applications involving alkynes and ketones.

PREREQUISITES
  • Understanding of alkyne and ketone structures
  • Familiarity with nucleophilic reactions

Can some one send me link that shows how a alkyne will react with a ketone. I have tryed google but found nothing.

Well you'll probably need to treat the alkyne with NaNH2 first, in order for it to react as a nucleophile towards the ketone. Otherwise, I'm not aware of any particular reactions of an alkyne in general and a ketone.
 
We reacted tetraphenylcyclopentadiene with diphenylacetylene while heating with a blow torch in silicone oil. Thats it, there where no bases
