摘要

Abstract 2-Aryl-2H-, 3-aryl-3H-, and 4-aryl-4H-azepine were formed by the novel, electrophilic, π LUMO-controlled reaction of the 2-methoxyazepinium ion, generated in situ by the reaction of TiCl 4 with 2, 7-dialkoxy-2H-azepine and an aryl compound, for which the kinetic parameters of the sigmatropic hydrogen rearrangement of the 4H-azepine was measured. The substitution and hydrogen shift of the azepinium ion were analyzed with ...
