Diene-conjugated nitrile ylides of the type 1a, having substituents other than hydrogen in the R1 position, cyclise normally to give the C-7b substituted cyclopropa[c]isoquinolines 2a. In cases where R2 or R3 = H the latter undergo the usual thermal rearrangement to give 5-substituted 2-benzazepines 5a. However, when R2 and R3 ≠ H and either is a CH3 group, then the presence of the C-7b substituent

The effect on the dibenzamide unit of replating one methyl H atom in N-methyldibenzamide with a 2-biphenyl substituent (giving the title compound, C27H21NO2) is seen primarily in the reduced pyramidalization at the central N atom.
