In this paper, a series of coumarin derivatives were synthesized, through the Pechmann condensation reaction using basalt fiber functionalized with 7‐aminonaphthalene‐1,3‐disulfonic acid (BF@(CH2)3‐Cl‐ANDSA) as environmentally friendly and heterogeneous catalyst. The structure of the catalyst was identified by FT‐IR, XRD, EDS‐Mapp, FE‐SEM, and TGA analysis. The catalyst was found to be efficient for the synthesis of coumarin derivatives through Pechmann condensation. phenols were treated with β‐ketoesters to give coumarin derivatives, under green conditions. The current method has several advantages, such as non‐toxic, short reaction time, high thermal stability, recyclability, and reusability of the catalyst.

“…The reactions went on well to afford products in good to high yields and short times. 37 It was obvious, which the recycle of a heterogeneous system and the lifetime of the catalyst are highly better in terms of green chemistry. This research used the reused catalytic five times without any reduction in the chemical reaction.…”

In this paper, hexamethylenetetramine-functionalized magnetic Fe 3 O 4 nanoparticles (Fe 3 O 4 @SiO 2 @Propyl-HMTA) catalyst was prepared and utilized for the synthesis of 4-aryl-NH-1,2,3triazole derivatives. Also, the interaction between aldehyde, nitromethane, and sodium azide was investigated within the synthesis route. Henry Reaction between the aldehyde and nitromethane created an intermediate that was immediately attacked by N 3 À . As a result of this attack, 4-aryl-NH-1,2,3triazole was generated through an in situ [3 + 2] cycloaddition.
