Abstract Model compounds for the (Z)- and (E)-3,4-Dihydro-5(1H)-pyrromethenon—5(4H)-Dipyrrylmethanon—system differently substituted in positions “3”, “4” and the N-atoms were synthesised. The solvent dependent equilibria between the derivatives with endo- and exocyclic double bond as well as those between the two diastereomers were studied. An investigation of the mechanistic aspects of the reactions leading to equilibration is included.
