Kinetics and reaction mechanism of iodination of diolefins with a bycyclo[3.3.1]nonane structure

To investigate the kinetics and reaction mechanism of iodination of diolefins with a bycyclo (3.3.1) nonane structure, the authors perform spectrophotometric analysis. They conclude that the transannular addition of iodine to these compounds in slightly polar and nonpolar media proceeds with the participation of donor-acceptor compounds of different composition. The charge separation in the intermediate complex, directly proceding the transitional state, should reach a minimal value necessary and sufficient for the effective intermolecular nucleophilic stage of the reaction.
