Application of benzotriazole methodology for the preparation of nitrogen-containing heterocyclic compounds is summarized in this review. The characteristic advantages of benzotriazole are first briefly considered followed by an overview of its use in the synthesis of heterocycles organized Author: Judit K.

Beagle. Phenyl(trimethylsilylethynyl)iodonium and tert-butyldimethylsilylethynyl(phenyl)iodonium triflates were applied to alkynylation of benzotriazole. Treatment of the silylethynyliodonium triflates with the potassium salt of benzotriazole ion in tBuOH and CH2Cl2 gave 2-(trimethylsilylethynyl)-2H-1,2,3-benzotriazole and 2-(tert-butyldimethylsilylethynyl)-2H-1,2,3-benzotriazole Cited by: The 1-(α-alkoxyalkyl)benzotriazoles are easily prepared: (a) by condensation of benzotriazole, an aldehyde, and an alcohol under water-removing conditions; (b) by condensation of a 1-(α.
