Abstract

The reactivity of R2TeHal2 (R= C6F5, 4-CF3C6F4; Hal= F, Cl, Br) towards AgCN and Me3SiCN was examined. The perfluoroaryl substituted tellurium (IV) difluorides reacted with AgCN and Me3SiCN to give the tellurium (IV) dicyanides (C6F5) 2Te (CN) 2 (1) and (CF3C6F4) 2Te (CN) 2 (2). Treatment of the corresponding tellurium dichlorides and tellurium dibromides with AgCN and Me3SiCN did not result in the formation of 1 and 2. ...
