Pentafluoroorthotelluric acid

F5TeO(CH2)2OTeF5, cis-[0(CH2)20]TeF4, and related compounds are formed in reactions of TeF with ethylene glycol and other polyhydric alcohols (69). The alkoxotellurium(VI) fluorides isolated so far are distillable liquids with considerable stability against hydrolysis. Some of these compounds have been prepared more easily by reacting diazoalkanes with pentafluoroorthotelluric acid (174), as in Eq. (11) ... [Pg.218]

In contrast to alcohols, trimethyl- and triphenylsilanol react with TeF to form the corresponding fluorosilane and pentafluoroorthotelluric acid (71). The system TeF6-ROH has also been studied by reacting Te(OCH3)6 with anhydrous hydrogen fluoride [Eq. (12)]. [Pg.218]

Xenon difluoride reacts with pentafluoroorthotelluric acid to give xenon(II) fluoride orthopentafluorotellurate. The latter reacts with AsF5 according to the equation (Eq. 27) —... [Pg.76]

An extremely versatile reagent for transferring F,TeO groups is boron tris(pentafluoroorthotellurate), B(OTeF,)3. Owing to its extraordinary Lewis acidity (2 77), a wide range of fluorides interacts with this compound, as in Eq. (19) (e.g., AsFs, SbF, XeF4, XeFg, MoF , WFg, UF ) ... [Pg.214]
