The tellurium-lithium exchange reaction: Selective functionalization of electron-deficient heteroaromatics

Electron-deficient heteroaromatic tellurides, which was obtained from the corresponding haloheteroaromatics, reacted selectively with n-butyllithium to give the lithio derivatives.

Lithiation of 1H-pyrazolo[3,4-d]pyrimidine derivative using lithium alkanetellurolate

4-Chloro-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine was converted into alkyl 1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-yl telluride, which was lithiated using alkyllithium followed by the reaction with electrophiles.
