Abstract

We have detected the unsymmetrical n faces of the olefin group in 2-substituted dibenzobicyclo-[2.2. 2loctatrienes (2-substituted 9, 10-dihydro-9, 10-ethenoanthracenes) and the carbonyl groups of 2-substituted and 3-substituted dibenzobicyclo [2.2. 2 Joctadienones (2-substituted and 3-substituted 9, 10-dihydro-9, 10-(1 l-ketoethano) anthracenes), wherein a-type overlaps of the n orbitals are involved, in a similar manner to ...
