A new thallium‐based supramolecular polymer [Tl(μ3–3‐HClb)(μ3–3‐Clb)]n (1), (3‐HClb = 3‐chloroperbenzoic acid), has been synthesized and structurally characterized by single crystal X‐ray crystallography. It has a two‐dimensional structure with linear thallophilic and covalent hydrogen‐bonding interactions. In order to evaluate the effects of concentration, ultrasonic irradiation and type of solvents on structure, morphology and thermal behavior of 1, some experiments were designed, and eight samples of 1 were synthesized under different conditions. These samples were characterized by IR spectroscopy, thermogravimetric and differential thermal analyses, X‐ray powder diffraction and scanning electron microscopy.

“…All the equatorial protons are deshielded to a large extent compared to the axial protons. The 13 C nmr spectrum of the compound (Figure 4) showed the characteristic thioureide signal at 195.5 ppm [26]. The α-carbon (cyclohexyl ring) appeared at 62.53 ppm and N-C(H 3 ) carbon appeared at 37.74 ppm.…”

In this study anhydrous AlCl3is used as a catalyst for the inclusion of a methylene group in to cyclohexylmethyldithiocarbamic acid to form methanediyl bis(cyclohexylmethylcarbamodithioate). Dichloromethane is used as a methylene group bearer in the reaction. A suitable mechanistic pathway involving+CH2Cl is discussed. FTIR, NMR and Mass spectral techniques have been used in the analysis. Single crystal X-ray structure of the compound was determined. FTIR spectrum of the compound showed υc-sband at 1073 cm-1and υC-Hvibrations appeared at 2853 and 2928 cm-1. Thioureide stretching band was observed at 1473 cm-1. The molecular ion peak in the Mass spectroscopy confirmed the proposed formula. H1NMR spectrum of the compound showed a signal at 4.33(s) ppm for α-CH of the cyclohexyl ring and -CH3protonsattached to nitrogen appeared at 3.40 ppm. Methylene proton (S-CH2-S) signal appeared at 3.16 ppm which is largely deshielded by the presence of two electronegative sulphur atoms on either side. The characteristic methylene carbon (S-CH2-S) signal appeared at 45.46 ppm in the13C NMR spectrum. Single crystal X-ray structural analysis of the compound showed it to be monomeric. Methylene carbon in S-CH2-S, C(9) is tetrahedrally bonded to two hydrogen atoms and two sulphur atoms S(2), S(3). The molecule stacks its cyclohexyl rings along ‘c’ axis of the unit cell. Short contacts in the form of supramolecular interactions such as C---S and S---S exist in the solid state at 3.49 and 3.50 Å respectively.

“…7 Furthermore, different transition metal complexes of dithiocarbamates have been synthesized for various studies, primarily because of their applications as organic superconductors. 8 In recent years, dithiocarbamates have been emerged as a novel class of potential agrochemicals (e. g. pesticides, 9 herbicides, 10 insecticides, 11 fungicides 12 etc.) such as carbamorph, ziram, benzathiazole derivatives etc.…”

A novel one-pot, solvent-free method for the synthesis of dithiocarbamates was developed through the reaction of corresponding alkyl halides, amines and carbon disulfide employing catalytic amount of benzyl trimethyl ammonium hydroxide (Triton-B). The reaction conditions are milder with extremely simple work-up procedures than the reported methods, afforded high yields (82-98%) of the desired products.
