2-(4-Chloroanilino)- and 2-(4-methoxyanilino)-1,2-diphenylethanone

Abstract

The title compounds, C20H16ClNO and C21H19NO2, adopt syn orientations of the C=O and N-H bonds but, like their analogues, form no strong intermolecular hydrogen bonds.

2-(4-Methoxy-2-methylanilino)-1,2-diphenylethanone

“…A few 1-arylanilinoethanone derivatives have been structurally charactized because of their importance in synthesis or because of their interesting charge-transfer properties (Abdulla et al, 1985). We found only four structurally similar compounds (Au & Tafeenko, 1987;Au & Tafeenko, 1986;Batsanov et al, 2006) in the Cambridge Structural Database (CSD CONQUEST 1.11, B4; Bruno et al, 2002).…”

“…For the synthesis and similar structures, see: Au & Tafeenko (1986; Batsanov et al, (2006). For general background to these structures, see: Batsanov et al (2006); Abdulla et al (1985). For bond-length data, see: Allen et al (1987).…”

“…The dihedral angle between the two phenyl rings is 87.78 (7) ° and the dihedral angle between the substitute aniline and phenyl rings are 55.30 (7) and 84.57 (7) °, respectively. In adition, in the title compound, the C2-C1-C8-N1-C15 backbone adopts an all-trans conformation (Au & Tafeenko, 1987;Au & Tafeenko, 1986;Batsanov et al, 2006).…”
