L'éthynylation des aldéhydes et cétones aliphatiques et cyclaniques en solution dans le méthylal et en présence de potasse caustique solide pulvérisée, conduit aux éthynylcarbinols avec des rendements satisfaisants. Le sel formé intermédiairement est l'alcoolate de l'éthynylcarbinol.

Organocuprates induce 1,3- and direct substitution in 3-alkyl- and 3,3-dialkyl-1-bromo-1,2-dienes leading respectively to either terminal acetylenes or allenic hydrocarbons. The nature of the cuprate exerts a prominent role in determining both the regio- and the stereochemistry of these reactions.

Analogues of the antimycotic allylamine terbinafine were prepared in which the naphthalene and the tert-butyl-acetylene moieties were preserved, but the spacer between these two groups was varied, and the antifungal activity of the new compounds was evaluated. All modifications of the original spacer such as reduction of the double bond, switching the position of the nitrogen atom, shortening, and
