Ethyl 2,6-bis-(4-chloro-phen-yl)-1-iso-cyano-4-oxo-cyclo-hexa-necarboxyl-ate.

ABSTRACT: In the title compound, C22H19Cl2NO3, the central six-membered ring is in a twist-boat conformation. The two aryl groups are in equatorial positions, trans to each other and with a dihedral angle of 77.50?(2)° between them. One of the least hindered -CH2- groups and one of the aryl-substituted C atoms, with its axial H atom, are in the flagpole positions. The eth-oxy-carbonyl group is in an equatorial position and is cis to the second aryl group. In the crystal, molecules are linked via weak C-H?O hydrogen bonds, forming chains along [010].
