Abstract

Reactions of PhTeCl3 with the dithiolate ligands (S2CNEt2)-, (S2P(OEt)2)-, and (S2COEt)- in solution were studied by variable-temperature 125Te, 31P, and 13C NMR spectroscopy, which show the formation of a variety of mixed-ligand species, some of which were subsequently isolated. MeTe(I)(S2CNEt2)2, formed by oxidative addition of Mel to Te(S2CNEt2)2, also provides a useful pathway to the synthesis of mixed-ligand species, but in general the products are less stable than the phenyl analogues. Solvent-dependent intramolecular exchange processes were observed for the alkyl and aryl series. The crystal and molecular structures of the mixed-ligand complexes bis(diethyldithiocarbamato)(O,O'-diethy..
