A series of tellurium(II) compounds containing tellurium/Group IVA element bonds of the general formula ArTeMPh3 (Ar = phenyl, p-tolyl, p-anisyl, p-bromophenyl; M = Ge, Sn, Pb) were prepared and examined by various chemical and spectroscopic means, including Raman spectroscopy, for characterization of metal-metal bond vibrations.These materials are air-stable, light-yellow solids, soluble in a variety of organic solvents, and an excellent source of the ArTe radical in reactions with transition metals.In reactions of these compounds with complexes of copper and palladium, the tellurium/Group IVA element bond was cleaved, with formation of transition metal complexes formulated as TeAr-bridged polymers.
