Formation of carbocations from bornan-2-exo-ol and its derivatives and their reactions with some nucleophiles

The reactions of bornan-2-exo-yl chloride and its isomers with carbon monoxide, acetonitrile, and water in antimony pentachloride–sulphur dioxide give bornan-2-exo-yl derivatives selectively. The reactions of bornan-2-exo-ol and its isomers with thionyl chloride showed marked dependence on the solvent used. The reactions of the alcohols with sulphuryl chloride are also reported.
