In the presence of diglyme bis(perfluoroorgano)tellurium-compounds (Rf)2Te (Rf=CF3, C6F5)) react with (CH3)2M (M=Zn, Cd) by stepwise Rf/R-exchange via CH3TeRf and CH3MRf to form (CH3)2Te and (Rf)2M*diglyme.A stoichiometric excess of (Rf)2Te favours the formation of CH3TeRf and (Rf)2M*diglyme; equimolar amounts react to (CH3)2Te and (Rf)2M*diglyme and an excess of (CH3)2M gives (CH3)2Te along with CH3MRf*diglyme.CF3TeCF3 is isolated in good yield by reacting (CH3)2M with (CF3)2Te in the ratio 1:2. (CF3)2Te also reacts with (C2H5)2M in the presence of diglyme to yield (CF3)2M*diglyme and C2H5)2Te.
