Abstract

Title full: Reactions of tellurium chloride pentafluoride, TeF5 Cl, with nitrogen nucleophiles. Preparation and characterization of the adducts (TeF4)2·NR2Cl, where R = CH3, C2H51 1 Presented in part at the 11th International Symposium on Fluorine Chemistry, East Berlin, G.D.R., August 1985; paper A-12, J. Fluorine Chem., 29 (1985) 34. Reactions of TeF5Cl with the nitrogen nucleophiles LiN=C(CF3)2, [(CH3)3Si]2NH, and (CH3)3SiNR2, Where R = CH3, C2H5, result in the reduction of the tellurium to Te(IV) and chlorination of the respective nucleophile. Analogous results are obtained in the reactions of TeF5Cl with (CH3)3SiCN, C6F5Li, and C6F5SLi. In the case of (CH3)3SiNR2, the new adducts (TeF4)2·NR2Cl are obtained in high yield. These compounds have been identified through their infrared, 1H, 19F, and 125Te NMR, and mass spectra as well as by elemental analysis.
