3-Chloropropeniminium salts 1 react with excess sodium azide in refluxing alcohols to give mainly 1-aryl-5-(2-dialkylamino-vinyl)-1H-tetrazoles 3; in minor quantities isomeric 5-aryl-1-(2-dialkylamino-vinyl)-1H-tetrazoles 4 are formed.The reaction involves splitting off N2 and C -> N migration of the aryl and dialkylaminovinyl group, respectively.A cross-over experiment indicated that the rearrangement step proceeds intramolecularly. - The i.r., u.v., and n.m.r. spectroscopic data of the novel 1H-tetrazoles 3 as well as the u.v. spectra of some new starting products 1k-v are reported.
