, p. 632 - 638 (2013)
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
Tresca, Blakely,Higbee, MacDonald,Mills, Nancy S.
experimental part, p. 5539 - 5546 (2011/08/21)
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
