In this study, magnetic multi-walled carbon nanotubes were functionalized with polyamidoamine (PAMAM) dendrimers and modified with butylsulfonate to afford MMWCNTs-D-(CH2)4-SO3H. The synthesized nanocomposite (MMWCNTs-D-(CH2)4-SO3H) was characterized by various techniques such as Fourier transform IR spectroscopy (FT-IR), transmission electron microscopy (TEM), SEM, XRD and thermo-gravimetric anal. (TGA). This nanocomposite catalyst effectively catalyzed four and three component reactions for the synthesis of dihydro-1H-indeno[1,2-b]pyridines I [R = H, 4-Me, 4-OMe, etc.] and tetrahydrobenzo[b]pyrans II [R1 = R2 = H, Me] (85-98% yield in 15-20 min and 80-98% yield in 12-30 min, resp.). In addition, the magnetically recoverable catalyst could be easily recycled at least five times without significant loss of catalytic activity. In the first step of synthesis of nanocomposite the Fe3O4 nanoparticles were deposited on oxidized MWCNTs, then a modified PAMAM dendrimer was used to bond to the carbonyl groups. Finally MMWCNTs-D-NH2 functionalized with 1,4-butanesultone. In addition to this study using 3-Hydroxybenzaldehyde, there are many other studies that have used 3-Hydroxybenzaldehyde(cas: 100-83-4Product Details of 100-83-4) was used in this study.
3-Hydroxybenzaldehyde(cas: 100-83-4) is used as an ionophore, during the development of an highly selective and sensitive PVC membrane sensor, which can be used as a Tb3+ ion selective electrode.Product Details of 100-83-4
