Ethyl 2-(5-bromo-2-iodo-anilino)cyclo-pent-1-ene-1-carboxyl-ate

摘要

In the title compound, C 14 H 15 BrINO 2 , the conformation of the C—O—CH 2 —CH 3 grouping is anti [torsion angle = 173.8?(6)°] and the bond-angle sum at the N atom bridging the two rings is 360°. An unusual intra-molecular bifurcated N—H?(O,I) hydrogen bond helps to establish the mol-ecular conformation, in which the I atom and the C=O grouping are syn . In the crystal, inversion dimers created by pairs of short inter-molecular C—I?O inter-actions [C—I = 2.080?(7)??; I?O = 3.211?(5)??; C—I?O = 152.4?(2)°] occur.
