Reaction of 1,3-cycloalkadienes (cyclopentadiene, cyclohexadiene, and cycloheptadiene) with iodine-cerium(IV) ammonium nitrate in alcohols, gave the corresponding regiospecific trans-2-alkoxy-1-iodo compounds as major products accompanied with 1,4-dialkoxy compounds as by-products.In the case of CH3CN-H2O as solvent, trans-iodohydrins were obtained.Thus the reaction of cyclic and acyclic i671,3-diene derivatives using this synthetic method afforded the 1,2-addition alkoxyiodo compounds preferentially.
Studies on Rearrangement of 3,6-Diaryloxycyclohexenes

Claisen rearrangement of 3,6-diaryloxycyclohexenes furnish a viscous oil which gives positive ferric chloride test and a solid acetyl derivative (IV) indicating the phenolic nature of th rearranged product.The acetyl derivative (IV) consumes one mol of bromine to give a dibromo derivative (V) which undergoes a base-catalysed cyclisation to give 2,4-(3'-p-cresoxypropano)-3-bromo-6-methylchroman (VII).
