“…It was found that the same yield was observed for 80 C and 100 C and, therefore, the 80 C was selected as the optimum temperature (Table 1, entries 6-10). In addition, the effect of different solvents was investigated, and it was found that water was more effective solvent (Table 1, entries 6,[11][12][13][14][15]. On the other hand, reaction under solvent-free conditions requires a temperature of 130 C (Table 1, entry 16).…”

“…The Fe 3 O 4 @C core-shell were prepared by our previous method. [14,15] Briefly, 0.1 g of Fe 3 O 4 as synthesized was dispersed in 25 ml distilled water containing 2.0 g glucose under ultrasonication for 30 min. The resulting mixture was transferred into autoclave of 50 ml stainless steel and heated at 200 C for 12 h with a 2 C/ min (note: temperature rating is important for carbonization of glucose in exact morphology; sonication of Fe 3 O 4 is important for core-shell achievement).…”

A green and stable magnetic Fe 3 O 4 core encapsulated in porous carbon shell was prepared. Then, the surface of as-synthesized Fe 3 O 4 @meso-C immobilized with activated 4-aminobenzenesulfonic acid to achieve Fe 3 O 4 @C/ Ph SO 3 H. Structural, physico-chemical, and magnetic properties of synthesized Fe 3 O 4 @C/Ph SO 3 H catalyst using various analyses such as FT-IR spectroscopy, TGA, XRD, SEM, TEM. EDX, and VSM were investigated. Fe 3 O 4 @C/ Ph SO 3 H was used as a stable and recoverable acid catalyst for regioselective three-component synthesis of tetrazoloquinazolines under mild conditions. This catalyst offers a green protocol of one pot due to having active SO 3 H groups, reacting in mild conditions with high yield and ability to recover and reuse without significant loss in activity.

A copper‐triazine‐dendrimer‐functionalized graphene oxide (CTD‐GO) is synthesized for the first time. The structure of the dendrimer is confirmed by Fourier transform infrared (FT‐IR), Fourier transform (FT) Raman, powder X‐ray diffraction (PXRD), X‐ray photoelectron spectroscopy (XPS), energy‐dispersive X‐ray spectroscopy (EDX), field emission scanning electron microscopy (FESEM), high‐resolution transmission electron microscopy (HRTEM), elemental mapping, atomic absorption spectroscopy (AAS), and thermogravimetric analysis (TGA). The catalytic activity of the CTD‐GO is demonstrated in green synthesis of a series of propargylamine derivatives in high yields via A3‐coupling of aldehyde, alkyne, and amine in water. After the reaction, the catalyst was easily recuperated from the reaction mixture and reused up to four times without any significant loss in its catalytic activity. Operational simplicity, high yields of product, use of green solvent, facile recovery and recyclability of the catalyst, and easy workup are the salient features of this procedure.

“…Core/shell nanostructures have been functionalized with magnetic dithiocarbamate deposited on gold and utilized as the catalysts for synthesizing propargyl amines through A 3 coupling reaction [44]. The catalyst displayed good performance for the synthesis of propargyl amines when phenylacetylene, benzaldehyde and morpholine were used as the starting material.…”
