A variety of heteroatom-substituted methyllithiums (GCH2Li; G = MeOCH2CH2O-, PhCH2O-, Me2N-, Me3Si-, Me3Ge-, nBu3Sn-, nBuTe-) were generated by the lithium-tellurium exchange reaction of corresponding tellurides with butyllithium and were trapped with electrophiles. The potent utility of bis(butyltelluro)methane as a methylene dianion synthon was demonstrated, where both of the butyltelluro groups were displaced stepwise by different electrophiles with use of this metalation/trapping sequence repeated twice.
