The tellurium–lithium exchange reaction: selective functionalization of electron-deficient heteroaromatics
摘要:
Electron-deficient heteroaromatic tellurides, which was obtained from the corresponding haloheteroaromatics, reacted selectively with n-butyllithium to give the lithio derivatives. (C) 2001 Elsevier Science Ltd. All rights reserved.

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. (C) 1999 Elsevier Science Ltd. All rights reserved.
