Intramolecularity of the Thermal Rearrangement of Allyloxytetrazoles to N-Allyltetrazolones†, Journal of Chemical Research, 5, 164-165, 1997.AUT: MCR00716;http://hdl.handle.net/10400.1/4267The intramolecularity of the thermal rearrangement of 1-aryl-5-allyloxy-1H-tetrazoles 1 to 1-aryl-4-allyl-1,4-dihydrotetrazol-5-ones 2 has been investigated through cross-over studies: the results support the hypothesis for a concerted sigmatropic rearrangement occurring through a highly polar transition state, in which a partially positively charged allyl group migrates from oxygen to nitrogen, without leaving the solvent cage.engjournal article2014-06-05http://dx.doi.org/10.1039/A608333A
