چکیده مقاله :
در این پژوهش با توجه به اهمیت استفاده از نانوکاتالیست ها در واکنش های آلی، کمپلکس سالن مس تثبیت شده بر روی نانو ذرات مغناطیسی کبالت فریت- هیدروکسی آپاتیت سنتز و با استفاده از روش های مختلف از جمله FT-IR، SEM، ICP، XRD و غیره شناسایی گردید. فعالیت کاتالیزگر در واکنش چند جزئی به منظور سنتز مشتقات اسپیرواکسیندول بررسی شد و محصولات با بازده بالا تهیه گردید. عدم استفاده از حلال های سمی، سهولت بازیافت و قابلیت استفاده مجدد از کاتالیزگر و عدم تشکیل محصولات جانبی، از مزایای این روش می باشد.
In this study, considering the importance of nanocatalysts in organic reactions, a copper salen complex supported on cobalt ferrite–hydroxyapatite magnetic nanoparticles(CoFe₂O₄@HAP@Cu Salen Complex) was synthesized and characterized using various techniques including FT-IR, SEM, ICP, XRD, etc. The activity of the catalyst in a multicomponent reaction was investigated for the synthesis of spirooxindole derivatives, and high-yield products were prepared. The absence of toxic solvents, easy recycling and reusability of the catalyst, and no formation of by-products are the advantages of this method.
