Attempts to produce 1-ethynylcyclopentanol from cyclopentanone and acetylene with various condensing agents did not give satisfactory results. A small amount of the acetylenic alcohol was obtained as a by-product in making the glycol (I) but not enough of the alcohol could be obtained to use it in other reactions. a-Tetralone was condensed with l- ethynylcyclohexanol-1 to give the unsymmetrical glycol (VIII) which in turn was ...
