We discuss the formation of new products in a solid – solid reaction in the capillary as in well as in bulk in the presence of an organic solvent impurity in a small amount. Three reactions namely KI + HgCl2, CuI + HgCl2and AgI + HgCl2were studied. It was found for some of the organic solvent impurities, a small amount of some substance appeared in the half occupied by HgCl2. Thus it became clear that some of the organic substances were reacting with HgCl2to produce a new substance which be an organo-metallic product. In this light HgCl2 was made to react with the different solvents. However, the new product could be separated out only in two cases, with Cyclohexanone and Dimethylsulfoxide. A black coloured product was formed with Cyclohexanone and with Dimethylsulfoxide the new product was of a light greenish colour. With the other solvents like Acetophenone and Nitrobenzene, the product, if formed, could not be separated out. So a preliminary study of the two products naming these as product A and product B formed with Cyclohexanone and Dimethylsulfoxide respectively has been done. The product A is formed by the reaction of Cyclohexanone solvent with HgCl2and product B is formed by the reaction of Dimethylsulfoxide solvent with HgCl2both at 80ºC, for 5 hours. The preliminary studies carried out were measurement of molecular weight (by elevation of boiling point method), ionicity, XRD, FTIR etc.
