Summary
-
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.
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%.
