Ethyl 2,6-bis(4-bromophenyl)-1-isocyano-4-oxocyclohexanecarboxylate

In the title compound, C22H19Br2NO3, the central oxocyclohexane ring is in a twist-boat conformation; all the substituents (one ethoxycarbonyl and two aryl groups) are located in equatorial orientations. One of the –CH2– groups and the opposite –CH– group bearing a bromobenzene substituent form the flagpoles of the twist-boat. The dihedral angle between the aromatic rings is 76.4 (4)°. In the crystal, weak C—H...O interactions link the molecules into C(5) chains propagating in the [010] direction. A short Br...O contact of 3.254 (4) Å is observed.
