Application of a biological‐based nanomagnetic catalyst in the synthesis of bis‐pyrazols and pyrano[3,2‐c]pyrazoles
Applied Organometallic Chemistry Vol. 31, No. 6
چکیده
{Fe3O4@SiO2@(CH2)3‐thiourea dioxide‐SO3H/HCl}, a newly reported nanomagnetic core–shell supported solid acid catalyst, was successfully employed in the preparation of 4,4′‐(arylmethylene)bis(1H–pyrazol‐5‐ol) and pyrano[3,2‐c]pyrazole derivatives. The presented methods are very efficient and high‐yielding. Also, the catalyst exhibited powerful potential for reusability in both types of reactions.
