详细
The immobilization of AlCl3, an extremely hygroscopic Lewis acid, on graphene oxide as a support material with a high surface area was studied. The obtained solid material was characterized by FTIR spectroscopy, TGA/DTA analysis, field emission scanning electron microscopy, and energy-dispersive X-ray spectroscopy and used as an efficient and bench-top environmentally benign catalyst for the preparation of bis (pyrazolyl)methane derivatives through the condensation of aldehydes and 3-methyl-l-phenylpyrazol-5-one. The catalyst is reusable for at least nine times with a negligible loss in its catalytic activity.
