Examination of the reactivity of bis(trifluoromethyl)tellurium: Oxidative trifluoromethylations and ligand exchanges with group 5A and 6A (15 and 16) elements and their halides

Bis(trifluoromethyl)tellurium reacts with I2, S8, Se, P4, and As at 220°C to afford CF3I, (CF3)2S, (CF3)2Se, (CF3)3P, and (CF3)3As, which are separated in 97, 92, 92, 70, and 46% yields, respectively. The interaction of (CF3)2Te with Sb at 170°C results in very small amounts of (CF3)3Sb, ca. 3%, but no (trifluoromethyl)germanes were observed when (CF3)2Te was exposed to Ge at 170°C. At 170°C the reactions of (CF3)2Te with SeBr4, PI3, and AsI3 generate (CF3)2Se, (CF3)3P, and (CF3)3As, which can be isolated in 98, 65, and 88% yields, respectively. The reaction of SCl2 with (CF3)2Te at 170°C, however, is less productive, presumably because there are several alternative pathways that are competitive with the reaction channel that leads to (CF3)2S. At 170°C SbI3 and (CF3)2Te form trace amounts (ca. 0.2%) of (CF3)3Sb, but in the temperature range 120-170°C, the reaction of GeI4 with (CF3)2Te gave no evidence for the formation of (trifluoromethyl)germanes.
Bis(trifluoromethyl)cadmium*glyme (glyme = dimethoxyethane), a New, Powerful Fluoroalkylating Agent and Low-temperature Source of Difluorocarbene

The newly isolated reagent (CF3)2Cd*glyme readily exchanges ligands with, e.g., GeI4, SnI4, or PI3 to form the fully substituted compounds (CF3)4Ge, (CF3)4Sn, or (CF3)3P, within minutes at ambient temperature; reactions with acyl halides, like MeC(O)Br, form the acyl fluorides, like MeC(O)F, in excellent yields, 95percent, at -25 deg C and extrusion of CF2 at -25 deg C in this reaction is indicated by the formation of the expected difluorocyclopopane from tetramethylethylene in 53percent yield.
