DIE REAKTIONEN VON BIS(PERFLUORORGANO)TELLUR-VERBINDUNGEN (Rf)2Te (Rf=CF3, C6F5) MIT DIALKYLCADMIUM- UND -ZINK-VERBINDUNGEN R2M (R=CH3, C2H5; M=Zn, Cd)

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.

(C6F5)Te(CH2)3NMe2 (1), a perfluorophenyltellurium derivative capable of forming intramolecular N???Te interactions, was prepared and characterized. The donor-free reference substance (C6F5)TeMe (2) and the unsupported adduct (C6F5)(Me)Te?NMe2Et (2 b) were studied in parallel. Molecular structures of 1, 2 and 2 b were determined by single-crystal X-ray diffraction and for 1 and 2 by gas-phase electron diffraction. The structure of 1 shows N???Te distances of 2.639(1) ? (solid) and 2.92(3) ? (gas). Ab initio plus NBO and QTAIM calculations show significant charge transfer effects within the N???Te interactions and indicate σ-hole interactions.
