Claesson, Alf published the artcileAllenes and acetylenes. I. Formation of conjugated dienes on lithium aluminum hydride reduction of allenic tert-alcohols, Safety of 2-((2-Methylbut-3-yn-2-yl)oxy)tetrahydro-2H-pyran, the publication is Acta Chemica Scandinavica (1947-1973) (1972), 26(6), 2540-2, database is CAplus.
The cyclohexanol I was refluxed 20 min with LiAlH4 in Et2O to give 72% of the cyclohexanol II. II was refluxed with LiAlH4 in THF under N to give 75% 2-propenylidenecyclohexane (III). I was refluxed with LiAlH4 in THF under N to give 70% of III. Similar results were obtained for the reaction of IV with LiAlH4 in Et2O and THF. LiAlD4 reduction of II gave 2-propenylidenecyclohexane-2-d.
