All the chemicals used were of analytical reagent grade and were used directly without further purification. The title compound was synthesized according to the reported method (Mahabaleshwaraiah et al., 2012). The compound is recrystallized by ethanol- chloroform mixture. Colourless needles of the title compound were grown from a mixed solution of Ethanol/Chloroform (V/V = 2/1) by slow evaporation at room temperature. Yield =72%; m.p.:405–407 K.
All H atoms were positioned geometrically, with C—H = 0.93 Å for aromatic H, C—H = 0.97 Å for methylene H and C—H = 0.96 Å for methyl H, and refined using a riding model with Uiso(H) = 1.5Ueq(C) for methyl H and Uiso(H) = 1.2Ueq(C) for all other H.
Synthetic
are widely used as aroma chemicals because of their odour strength, tenacity, stability to alkali and relatively cheap price; applications include their use as a sweetener and fixative (in perfume); fragrance enhancers (for natural essential oils); blenders (in soaps and detergents); aroma enhancers (in tobacco); and for imparting pleasant odours to industrial products. The have been the subject of extensive studies because of their interesting biological activities and have, in fact, been used as therapeutic agents for the treatment of various diseases. show quite diverse biological activities, including anticoagulant, anti-allergic, anthelmintic, diuretic, insecticidal and antibiotic properties (Trkovnik et al., 1983); Rao et al., 1981). The great of the nitrogen atom as compared to that of sulfur makes the latter more acidic and an in the nucleophilic attack. The fact is that the sulfur anion formed is more stabilized by negative charge distribution. Furthermore, functionalized are an important class of compounds and their medicinal and biological properties warrant study (D'hooghe et al., 2006). Organic dithiocarbamates are valuable synthetic intermediates (Boas et al., 2004), which are ubiquitously found in a variety of biologically active compounds. Functionalization of the carbamate moiety offers an attractive method for the generation of derivatives, which may constitute interesting medicinal and biological properties (Fernández et al., 1995).The compound herein reported, (7-chloro-2-oxo-2H-chromen-4-yl)methyl dimethylcarbamodithioate (Fig. 1) presents a planar 2H-chromene ring system [maximum deviation: 0.005 (2) Å for atom C13]. The π–π interactions between fused benzene rings of chromene [shortest centroid–centroid distances = 3.6553 (13) Å and 3.5551 (13) Å]. A packing view is shown in Fig. 2.

Experimental. IR (KBr, cm-1): 1722 (C=O), 1381 (C=S), 894(C—N). GCMS: m/e: 313; 1H NMR (400 MHz, CDCl3, \?, p.p.m): 3.38 (s, 3H, N—CH3), 3.47 (s, 3H, N—CH3), 4.80 (s, 2H, C4—CH2), 6.56 (s, 1H, C3—H), 7.45–7.92 (m, 3H, Ar—H). Mol. Formula: C13H12Cl N O2S22; Elemental analysis: C, 49.75; H, 3.85; N, 4.46 (calculated); C, 49.67; H, 3.76; N, 4.39 (found). |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Synthetic coumarins are widely used as aroma chemicals because of their odour strength, tenacity, stability to alkali and relatively cheap price; applications include their use as a sweetener and fixative (in perfume); fragrance enhancers (for natural essential oils); blenders (in soaps and detergents); aroma enhancers (in tobacco); and for imparting pleasant odours to industrial products. The coumarins have been the subject of extensive studies because of their interesting biological activities and have, in fact, been used as therapeutic agents for the treatment of various diseases. Coumarins show quite diverse biological activities, including anticoagulant, anti-allergic, anthelmintic, diuretic, insecticidal and antibiotic properties (Trkovnik et al., 1983); Rao et al., 1981). The great electrophilicity of the nitrogen atom as compared to that of sulfur makes the latter more acidic and an active centre in the nucleophilic attack. The fact is that the sulfur anion formed is more stabilized by negative charge distribution. Furthermore, functionalized carbamates are an important class of compounds and their medicinal and biological properties warrant study (D'hooghe et al., 2006). Organic dithiocarbamates are valuable synthetic intermediates (Boas et al., 2004), which are ubiquitously found in a variety of biologically active compounds. Functionalization of the carbamate moiety offers an attractive method for the generation of derivatives, which may constitute interesting medicinal and biological properties (Fernández et al., 1995).
The compound herein reported, (7-chloro-2-oxo-2H-chromen-4-yl)methyl dimethylcarbamodithioate (Fig. 1) presents a planar 2H-chromene ring system [maximum deviation: 0.005 (2) Å for atom C13]. The crystal structure shows intermolecular C—H···S bonds·(C16-H16A···S3, H···S= 2.84 Å; C-H···S: 150°) and π–π interactions between fused benzene rings of chromene [shortest centroid–centroid distances = 3.6553 (13) Å and 3.5551 (13) Å]. A packing view is shown in Fig. 2.
