Ethynyl cyclohexanol??


Can it really be so easy?
CaC2 + 2H2O → Ca(OH)2 + C2H2
C2H2 + C6H10O → C8H12O
Bubbling acetylene in to cyclohexanone??

I don't have a cite, but I'd be very surprised if it was that easy.

If you reacted sodium acetylide (NaCCH) with cyclohexanone, and then quenched the product with water, you should get the desired product.

Oh just foun this
http://en.wikipedia.org/wiki/Ethinamate

Ethinamate is synthed form ethynyl cyclohexanol.

so as i understand acetylene reacts with cyclohexanone when something like lithium is used to start reaction.
Im not really that smart so it would be cool to get some feedback

Nope, you would have tondeprotonate the alkyne first. Refer to basic textbooks on organic chemistry.

The cyanide ion can reversibly react with ketones in the same way. And acetylene is known to react with solutions of silver salts, forming silver acetylide precipitates. So my guess is that it is possible, although it might require some type of catalyst.

(see the Cyanohydrin reaction)




I'm not saying let's go kill all the stupid people...I'm just saying lets remove all the warning labels and let the problem sort itself out.
