Stable arylnitrile oxides were able to react with 5-aryltetrazoles in the presence of tertiary amine, giving open-chain addition products with the structure of 2,5-disubstituted tetrazoles.Kinetic measurements were performed at 35 deg C, mostly in chloroform in the presence of triethylamine.Substituents on the tetrazole benzene ring had almost no effect, but for substitution on the nitrile oxide benzene ring a non-Hammett-like effect was found.Rates were higher in CHCl3 than in (CHCl3 + 10percent MeOH), and with Et3N than with PhMeN.The reaction mechanism is discussed.
