Source of material

The reagents and solvents used in this study are commercially available. The synthesis of (bis(methylthio)methylene)-1-phenylbutane-1,3-dione was carried out according to following procedure:

A solution of dimethylformamide (40 mL) and 1.62 g (0.01 mol) of 1-phenylbutane-1,3-dione, and 5 g of K2CO3 were treated drop wise with 1 mL of carbon disulphide for 1 h at 25 °C with stirring. This mixture was further stirred for 1 h with 82 g (0.02 mol) of iodomethane, continued for further 3 h and the reaction mixture was poured into ice-water. The precipitated product was filtered and dried; the precipitated was recrystallized from ethanol.

Yield: 86%; m.p. 55 °C; IR (νmax): 3054, 2991, 2926, 1646, 1578, 1423, 1262 cm−1; 1H-NMR (400 MHz, CDCl3): δ 2.17 (s, 3H, CH3), 2.23 (s, 3H, CH3), 2.50 (s, 3H, CH3), 7.28–7.92 (m, 10H, Ph); 13C-NMR (100 MHz, DMSO-d6): δ 18.5, 18.9, 28.9, 128.9, 129.6, 135.0, 138.9, 140.1, 155.4, 194.6; MS m/z (%): 266.04 [M+, 60%]; Anal. calcd. for C13H14O2S2: C, 58.62; H, 5.30; S, 24.07%; Found: C, 58.61; H, 5.31; S, 24.10%.

Discussion

Impressive biological properties displayed by privileged nucleus of ketene N,N- and N,S-acetals have triggered the development of a variety of methods for their synthesis [1]. The crystal structure of target compound consist of six membered ring (C8—C13) which is bonded to the ketene S,S-dithioacetal moiety. The molecules packing in the crystal structure is stabilized by two intermolecular hydrogen bonds.
