Introduction of BIS (TRIFLUOROMETHYL) MERCURY

        Because of fluoride elimination of trifluoro methylated the syntheses organometallics exceptional method required these are not readily accessible like Grignard-type reagents CF₃MgX. In the preparation of frequent derivatives of CF₃ Bis (trifluoro methylated) mercury is used, especially for group IV element. In 1949 it was first prepared through irradiation of CF₃I as well as mercury (Hg) within the presence of Cadmium (Cd). Radiofrequency discharge methods are the alternatives techniques routes are including such as with HgX₂ reaction of CF₃ radicals.

        In the presence of carbonate by decarboxylation of mercury trifluoroacetate preparative scale quantities are best. Mercury is highly poisonous compounds. Direct contact with this compound is avoided.  In a well-ventilated hood the entire procedure should be carried out. We should wear protective gloves as well as a face shield. A corrosive strong acid is known as trifluoroacetic acid. It should be prevented from the contact with the skin. For toxic heavy metal derivatives residues disposal should match the all safety requirements (Eujen & Lagow, 1978).

Experimental of BIS (TRIFLUOROMETHYL) MERCURY

    With a magnetic stirrer, two moles of HgO 433g is dissolved in 320 mL solution of trifluoroacetic acid in a 2-L round bottomed flask. To avoid crystallization of the   white, enough H₂O is added to the solution. Through the rotary evaporator excess acid as well as water is removed. In a dry atmosphere the residue of solid is finely powdered, at 120 degree dried under vacuum, with 500 g of K₂CO₃ carefully mixed in the solution as we can see in the picture of the setup of 

        Through a silicon-oil bubbler by-passed the reaction to an oil pump tube is attached as well as also acetone slush bath (Graner, et al.). The pressure in the system by means of a leak valve might be adjusted that is open to the air. For another twenty-four hour to 100 degree the reaction mixture is heated. The pressure is increased up to 25 torr by-pass valves is closed after that and also a temperature is enlarged up to 120 degree at that time CO₂ evolution begins. Over a period of 3 days the furnace temperature is increased to 180 degree, to maintain the constant evolution of CO₂ a temperature being adjusted. The reaction tube on the cooler part  as white crystal that is formed condenses. By reduction of the rate of liberation of CO2 is indicated at the end of the reaction and the formation of elemental mercury increased. 90% yield is obtained for small scale preparations (Eujen, Gomes, & Morrison, 2007).

Result & discussion of BIS (TRIFLUOROMETHYL) MERCURY

    With methyl derivatives of group 4 elements Bis (trifluoromethylated) mercury was treated compounds by reaction. Here we drive the chemical equation

    The ease of this reaction increases with the decrease of M-C bond strength: here on the above equation there is no reaction with the other element of this group. At the temperature of 120 to 180 when  is added to the solution then we get the desired BIS (TRIFLUROMETHYL) mercury. Whereas no reaction SiMe₄ as well as GeMe₄ it changed only one methyl group. As if we start the SiMe₄ could be exchange the second methyl group, by low conversion the yield of SnMe₂ was limited at the reaction temperature by extensive decomposition. By this method amazingly a second trifluoromethyl group could not be transferred to lead. On the other hand, NMR spectral evidence for  was obtained when  is treated with .

Conclusion of BIS (TRIFLUOROMETHYL) MERCURY

    It is concluded that by the reaction of mercury trifluoromethylated were obtained this is thermally unstable compound and also Bis (trifluoromethylated) mercury in solution as well as by multinuclear NMR characterized spectroscopy. Thermal stability increase that is observed 18 valence electron complexes product is formed. In a distorted tetrahedral fashion the mercury ato
