Investigations on the preparation of trifluormethyl compounds of the elements mercury, tellurium, and xenon

(CF3)2Hg is formed from the reactions of C2F6 with Hg, HgX2 (X = Cl, Br, I) or HgO in a chemical plasma. The best yields are obtained with Hg and HgO. The reaction of C2F6 with Te yields (CF3)2Te2, which also can be identified in small amounts from the reactions of C2F6 with TeX4 (X = Cl, Br). A similar reaction with Xe does not give any evidence for the formation of a noble gas compound. (author)
