The Friedel-Craft's electrophilic substitution on 2,6,6-trimethylbicyclohept-2-ene (I) (α-pinene) with acetic, propionic and butyric anhydrides at 95 deg C in presence of anhyd.ZnCl2 gives a mixture of three products in each case.Two of them are position isomers (II, III) due to double bond while the third product (IV) is formed by the opening of cyclobutane ring of I.Their structures have been established by spectral studies.
