Could use the cyclohexanone for production of ethynylcyclohexanol, a fairly potent sedative, structurally most similar to some of the oldschool downers such as ethchlorvynol, and in a similar vein to the latter, 2-methyl-butan-2-ol, and the like, as far as action goes.
React with sodium acetylide (produced by solvating Na metal in a suitable amine, saturated with acetylene gas. Liquid ammonia would definately work, but seeing as it takes the role of a solvent only, I believe EDA would probably work. Not too familiar with TETA but I wouldn't be surprised, followed by slow! addition of metallic sodium or potassium. Cessation of the acetylene flow into the amine before the addition of cyclohexanone is complete apparently encourages the formation of ethynylcyclohexanediol.
I bet you could use calcium carbide also, avoiding the use of an amine solvent for the production of the acetylide, CaC2 is pretty cheap.
Easier in practise, avoiding the use of liquid NH3, or other nasty amines, would be the simpler reaction of the enol tautomer of cyclohexanone (using NaOMe) with acetylene gas.
