Cobalt (II) Schiff base complex immobilized on cobalt ferrite magnetite nanoparticles as a reusable catalyst for the preparation of triazoloquinazolinones
摘要
Cobalt (II) Schiff base complex was placed on the cobalt ferrite magnetite nanoparticles and applied as a heterogeneous and reusable catalyst for the preparation of triazoloquinazolinone derivatives. Cobalt (II) complex by the rearrangement from tetrahedral to square planer structure and then increase the coordination number of cobalt can be accelerate the catalyze the condensation reaction of 3-amino-1,2,4-triazole with aromatic aldehyde and dimedone.
