In the presence of diglyme bis(perfluoroorgano)tellurium-compounds (R_f)2Te (R_f=CF3, C6F5)) react with (CH3)2M (M=Zn, Cd) by stepwise R_f/R-exchange via CH3TeR_f and CH3MR_f to form (CH3)2Te and (R_f)2M*diglyme.A stoichiometric excess of (R_f)2Te favours the formation of CH3TeR_f and (R_f)2M*diglyme; equimolar amounts react to (CH3)2Te and (R_f)2M*diglyme and an excess of (CH3)2M gives (CH3)2Te along with CH3MR_f*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.
