    2-chlorocycloalkanones with vinylmagnesium chloride gives 1,2-divinylcycloalkanols. Divinylation proceeds via a rearrangement of initially formed 2-chloro-1-vinylcycloalkanols to 2-vinylcycloalkanones followed by further vinylation of 2-vinylcycloalkanones. Thermal sigmatropic rearrangement of 1,2-divinylcycloalkanols gives 5-cycloalken-1-ones in good yields. The influence of the size of rings on the

    2-divinylcyclododecan-1-ol, which was easily converted to 5-cyclohexadecen-1-one. This one-step divinylation was found to proceed not through a direct displacement of the Grignard reagent with the chlorine atom, but through a pinacol-like rearrangement of a vinyl group.

    This invention relates to a process for producing 5-cyclohexadecen-1-one continuously from 1,2-divinylcyclododecanol in a short time in an efficient manner without no side reaction. In the process, 1,2-divinylcyclododecanol as starting material is supplied from a raw material container 1 by a fixed delivery pump 2 to a flash unit 3 which is vacuumed to 5 mm Hg (666.5 Pa) or less by a vacuum pump 8 and is heated and 1,2-divinylcyclododecanol which is flashed in the flash unit is supplied to a reactor 4 which is heated to 400 to 650°C and vacuumed to 5 mm Hg (666.5 Pa) or less whereby 1,2-divinylcyclododecanol is converted into 5-cyclohexadecen-1-one. The reaction product is discharged from the top of the reactor and is cooled to recover the objective 5-cyclohexadecen-1-one in the recovery container 6. The reduction in the pressure of the apparatus is preferably performed by a vacuum pump 8 via a hydrochloric acid trap 7 comprising, for example, sodium methylate/methanol cooled to -78 to -100°C.
