Resumen:
The one-pot synthesis of dibenzo[b,d]azepin-7-one (3) wasselectively achieved from 1-phenacyl-1,2,3-benzotriazole (1) using thecatalytic flash vacuum pyrolysis (cfvp) methodology. Catalysts with thescheelite structure ABO4 (A = Ca2+, Sr2+, Ba2+ and B = Mo6+, W6+) andfergusonite BiVO4 were explored in this new catalytic reaction. Theseoxides promoted high conversion of starting material at lower temperaturesthan those observed for noncatalytic reactions. The chemical nature of Aand B cations in the scheelite structure showed a strong influence on theformation toward the desired azepinone. In addition, the catalyst?smorphology had a significant influence on the course of the cfvp reaction.
