An unusual example of the abnormal Wolff rearrangement was studied. The bicyclic structure of the reactant and intermediates precluded some mechanistic possibilities of this unusual Abnormal Wolff Rearrangement. The study involved the photochemical rearrangement of diazodehydronorbornone bearing phenyl and 2-pyridyl groups at C-7. A number of examples of interesting stereoselectivity were encountered. The mechanism was investigated by use of ab initio QST type computations which located a unique transition structure species accounting for the reaction mechanism.Key words: abnormal-Wolff, carbene, rearrangement, QM computations, reaction mechanism.
