An analysis of C-HO and C-H interactions in three substituted 4-ketotetrahydroindoles

A. R. Choudhury, K. Nagarajan and T. N. Guru Row

Abstract: The crystal and molecular structures of the three 4-ketotetrahydroindoles 2-(4-chlorophenyl)-1-(4-fluorophenyl)-6,6-dimethyl-4,5,6,7-tetrahydro-1H-indol-4-one (C₂₂H₁₉ClFNO), (I), 1-(4-fluorophenyl)-2-(4-methoxyphenyl)-6,6-dimethyl-4,5,6,7-tetrahydro-1H-indol-4-one (C₂₃H₂₂FNO₂), (II), and 6,6-dimethyl-1,2-diphenyl-4,5,6,7-tetrahydro-1H-indol-4-one (C₂₂H₂₁NO), (III), have been determined via single-crystal X-ray diffraction in order to study the intermolecular interactions therein. All three structures are stabilized via intermolecular C-HO and C-H [bold pi] interactions, generating different molecular motifs.

Formula: C₂₂H₁₉ClFNO, C₂₃H₂₂FNO₂ and C₂₂H₂₁NO
