  1. 1.

    The ethynylation of cycloaliphatic ketones was studied. With sodium acetylide,3-cyclohexen-1-ylketones condense rather worse than the corresponding cyclohexyl ketones do.

  2. 2.

    In their condensation with lithium acetylide cyclohexyl, 3-cyclohexen-1-yl, and 1-cyclohexen-1-yl ketones form tertiary acetylenic alcohols with equal ease in yields of 70–80%.
