Alkylation of Triethylamine Tetrazolate by Electrophilic Reagents

Probable direction of electrophilic attack

Two examples of reactions of triethylamine tetrazolate with electrophilic reagens

In the case that R=Ar or another bulky groups , the N2-isomer (YI) is obtained primarely [1,2].

In this untypical case only N2-isomers for all R have been obtained [3].

We are studying now a the mechanism of this process by kinetic methods.
