Abstract

The conformation of the title molecule, C₁₃H₁₄Cl₂N₂O₃, is maintained by intramolecular N—H⋯O, C—H⋯O, and C—H⋯Cl interactions, creating S(6), S(5), and S(6) motifs, respectively. In the crystal, intermolecular N—H⋯O, C—H⋯O, and C—H⋯Cl interactions connect the molecules, forming a three-dimensional network. Additionally, the molecules are linked by C—H⋯π interactions, forming layers parallel to the (002) plane. The most important interactions, according to Hirshfeld two-dimensional fingerprint plots, are H⋯H (35.0%), O⋯H/H⋯O (21.2%), Cl⋯H/H⋯Cl (20.7%), and C⋯H/H⋯C (17.1%).

1. Chemical context

Bisamidals are an important class of organic compounds, since the amide fragment is a component of many biologically active substances and is widely used in pharmaceuticals, medicine and materials science (Manne et al., 2017 ▸; Zhang et al., 2013 ▸). Bisamidals are also convenient starting reagents for the synthesis of heterocyclic and organophosphorus compounds with useful properties (Dmitriev et al., 2021 ▸; Makra et al., 2022 ▸). The catalytic and analytic properties of this class of compounds are strongly dependent on the attached groups to the amide moiety (Alieva et al., 2006 ▸; Aliyeva et al., 2024 ▸). Both the NH and C=O groups of bisamidals can participate in various sorts of intermolecular interactions, which improve the catalytic and biological activity of corresponding metal complexes (Kopylovich et al., 2012a ▸,b ▸; Mahmudov et al., 2015 ▸). We have previously shown that accessible highly electrophilic α,α-dihalogen-β-oxoaldehydes readily condense with amides to form amidals (Guseinov et al., 1994 ▸,2024 ▸ and 2025 ▸). We used this property of aldehydes (1) to obtain bisamidals (4). We found that bisamidals can be synthesized with a yield of 92% by reacting aldehydes with acetonitrile in the presence of concentrated sulfuric acid at room temperature. The formation of product (4) occurs via amide (2) and amidals (3) according to the scheme shown in Fig. 1 ▸. The structure of the product (4) was proven by NMR spectroscopy and X-ray diffraction.

2. Structural commentary

As shown in Fig. 2 ▸, the molecular conformation is not planar. Intramolecular N—H⋯O, C—H⋯O, and C–H⋯Cl interactions maintain the molecular conformation, forming S(6), S(5), and S(6) motifs (Bernstein et al., 1995 ▸), respectively. The C9—C4—C3—O3, C9—C4—C3—C2, C4—C3—C2—Cl1, C4—C3—C2—Cl2, C3—C2—C1—N10, C3—C2—C1—N13, C2—C1—N10—C11 and C2—C1—N13—C14 torsion angles are 14.8 (3), −162.76 (19), 46.2 (2), −73.6 (2), 63.4 (2), −64.2 (2), 125.26 (18) and −119.66 (19)°, respectively. The molecule exhibits no unusual bond lengths or inter-bond angles.

3. Supramolecular features and Hirshfeld surface analysis

In the crystal, the molecules are linked into a three-dimensional network by intermolecular N—H⋯O, C—H⋯O, and C—H⋯Cl interactions (Table 1 ▸, Fig. 3 ▸). In addition, the molecules create layers parallel to the (002) plane through C—H⋯π interactions (Table 1 ▸, Fig. 4 ▸). No π–π interactions are observed in the structure.

The intermolecular interactions (Tables 1 ▸ and 2 ▸) in the title compound were analysed using Hirshfeld surface calculations, employing CrystalExplorer 17.5 (Spackman et al., 2021 ▸). The Hirshfeld surface plotted over d_norm is shown in Fig. 5 ▸. The two-dimensional fingerprint plots (Fig. 6 ▸) show that the most significant contacts are H⋯H (35.0%), O⋯H/H⋯O (21.2%), Cl⋯H/H⋯Cl (20.7%), C⋯H/H⋯C (17.1%), Cl⋯Cl (2.1%), O⋯C/C⋯O (2.0%), O⋯N/N⋯O (0.9%), O⋯O (0.7%) and N⋯H/H⋯N (0.2%).

5. Synthesis and crystallization

To a solution of 217 mg (1 mmol) of 2,2-dichloro-3-oxo-3-phenylpropanal in 10 ml of acetonitrile was added sulfonic acid (2 mmol) at room temperature. The reaction mixture was then stirred for 1h. The solvent was removed in vacuo, the remaining white powder was recrystallized from chloroform and N,N′-(2,2-dichloro-3-oxo-3-phenylpropane-1,1-diyl)diacetamide was isolated. Yield 292 mg (92%); m.p. 378–380 K. Analysis calculated (%) for C₁₃H₁₄Cl₂N₂O₃: C 49.23, H 4.45, N 8.83, found C 45.18, H 4.41, N 8.82. ESI–MS: 316.0410. ¹H NMR (300 MHz, DMSO-d₆): 1.87 (6H, 2CH₃), 6.95-8.10 (5H, Ar), 8.4 (2H, 2NH). ¹³C NMR (75 MHz, DMSO-d₆): 22.24, 60.28, 89.93, 128.46, 129.83, 131.99, 133.77, 168.95, 187.35.

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. The N-bound hydrogen atoms were located in a difference-Fourier map and refined freely [N10—H10 = 0.84 (3) and N13—H13 = 0.83 (3) Å]. The C-bound H atoms were positioned geometrically (C—H = 0.95 and 1.00 Å) and refined using a riding model with U_iso(H) = 1.2 or 1.5U_eq(C). The title compound was refined as an inversion twin with matrix [−1 0 0 0 − 1 0 0 0 − 1]; the resulting BASF value is 0.273 (14).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
