Hydrogen iodide, reaction with cyclohexene

The occurrence of an Ad 3 mechanism has also been shown in the reaction of hydrogen iodide with cyclohexene in acetic acid Moreover this mechanism seems to apply equally well to the addition of HCl to acetylenic systems ... 

Apart from the reaction of cyclohexanecarboxylic acid with methyllithium, cyclohexyl methyl ketone has been prepared by the reaction of cyclohexylmagnesium halides with acetyl chloride or acetic anhydride and by the reaction of methylmagnesium iodide with cyclohexanecarboxylic acid chloride. Other preparative methods include the aluminum chloride-catalyzed acetylation of cyclohexene in the presence of cyclohexane, the oxidation of cyclohexylmethylcarbinol, " the decarboxylation and rearrangement of the glycidic ester derived from cyclohexanone and M)utyl a-chloroj)ropionate, and the catalytic hydrogenation of 1-acetylcycIohexene.

Cerveny et al. (69), attempted to apply the Drougard-Decroocq equation (34) to the data obtained in the hydrogenation of cyclohexene and 1-hexene on the catalyst 5% Pt on silica gel in 19 solvents. Since correlation of the reaction rates with the parameters of solvents x, originally obtained for the homogeneous Menschutkin reaction (88) between methyl iodide and tri-propylamine was unsuccessful, an analogous definition was used for the parameters x, which were to characterize the solvent with respect to its effect in heterogeneously catalyzed reactions ...
