Photolysis of dibenzo[a,d]cycloheptene dimer

Photolysis reaction of dibenzo[a,d]cycloheptene dimer 3 provides three dibenzo[a,d]cycloheptyl dimmers 4, 5 and 6 under different irradiation conditions via the intramolecular degradative cyclodimerization. A tetracyclic benzo[4,5]cyclohepta[1,2,3-de]naphthalene core is also synthesized.

Reduction of benzylidene dibenzo[ a, d ]cycloheptenes: Over-reduction of antiaromatic dianions to aromatic tetraanions

The antiaromaticity of a series of dianions of p-substituted benzylidene dibenzo[a,d]cycloheptenes was examined through calculated measures of antiaromaticity. The nucleus-independent chemical shifts (NICS) and magnetic susceptibility exaltation both show
