Preparation of bis(trifluoromethyl)tellurium, bis(trifluoromethyl)selenium, bis(trifluoromethyl)diselenium, tris(trifluoromethyl)antimony, tris(trifluoromethyl)arsine, bis(trifluoromethyl)arsenic iodide, tris(trifluoromethyl)phosphine, and (trifluoromethyl)phosphorus diiodide by reaction of bis(trifluoromethyl)mercury with the group 5 and 6A (15 and 16) halides

The reactions between Hg(CF3)2 and representative halides of the lower elements of main groups 5 (15) and 6A (16) have been investigated. At 155°C the reaction between TeBr4 and Hg(CF3)2 affords Te(CF3)2 in 92% yield. In 4.5 h at 210°C SeBr4 and Hg(CF3)2 form Se(CF3)2 and Se2(CF3)2 in 67% and 3% yields, respectively; in 2.5 h at 170°C they generate Se(CF3)2 and Se2(CF3)2 in 26% and 57% yields, respectively. At 165°C SbI3 and Hg(CF3)2 produce Sb(CF3)3, 63%. The interaction of AsI3 and Hg(CF3)2 can result in either As(CF3)3, 75%, or As(CF3)2I, 54%. Similarly, exposure of PI3 to Hg(CF3)2 can synthesize either P(CF3)3, 55%, or P(CF3)I2, 37%. In general, these reactions are more convenient than the classic route pioneered by Emeleus and his students, the interactions of trifluoromethyl iodide with the elements.
