ChemInform Abstract: Reactions of Tellurium Chloride Pentafluoride, TeF5Cl, with Nitrogen Nucleophiles. Preparation and Characterization of the Adducts (TeF4)2·NR2Cl, Where R = CH3, C2H5

Reactions of TeF 5 Cl with the nitrogen nucleophiles LiN=C(CF 3 ) 2 , [(CH 3 ) 3 Si] 2 NH, and (CH 3 ) 3 SiNR 2 , Where R = CH 3 , C 2 H 5 , result in the reduction of the tellurium to Te(IV) and chlorination of the respective nucleophile. Analogous results are obtained in the reactions of TeF 5 Cl with (CH 3 ) 3 SiCN, C 6 F 5 Li, and C 6 F 5 SLi. In the case of (CH 3 ) 3 SiNR 2 , the new adducts (TeF 4 ) 2 ·NR 2 Cl are obtained in high yield. These compounds have been identified through their infrared, 1 H, 19 F, and 125 Te NMR, and mass spectra as well as by elemental analysis.
