Ab Initio/IGLO Study of Strained Bicyclic Olefins
The 13C NMR chemical shifts of strained olefins 1, 2, 3, and 6 were calculated using the ab initio/IGLO method(DZ/6-31G*). The calculated values resemble the experimental data closely but show a systematic drift with increased strain. The chemical shifts of the yet unknown olefins 1 and 2 were predicted to be extremely deshielded.
