Selenium—Tellurium Sequences in Binary Glasses as Depicted by 77Se and 125Te NMR.

Low-temperature 1H, 13C, 77Se, and 125Te

Low-temperature 1H, 13C, 77Se, and 125Te NMR studies on the apical-apical ligand exchange via the hypervalent tellurium and selenium ate complexes [10-M-3(C3); M = Se, Te] in the reactions of diaryl tellurides and selenides with aryllithium reagents

Pentafluorophenyl phenyl telluride (1) and 3,5-dichloro-2,4,6-trifluorophenyl phenyl telluride (2) react with pentafluorophenyllithium or 3,5-dichloro-2,4,6trifluorophenyllithium in THF at low temperatures to form the corresponding tellurium ate complexes (A) and (B) as sole intermediates in the lig
