ZnO anchored on pine cone-derived porous carbon (PC@ZnO NPs) enables green synthesis of 2-amino-4 H -benzo[ b ]pyrans under solvent-free conditions at room temperature, highlighting biomass valorization into a high-value catalyst.

Correction for ‘γ-Fe₂O₃@Zn-LDH-EAE-SO₃H for multi-component synthesis of chromeno[4,3-b]quinoline-6,8-dione derivatives’ by Ahad Vatandoust Namanloo et al., RSC Adv., 2025, 15, 21465–21478, https://doi.org/10.1039/D5RA03659C.

A novel method for preparing chromeno[4,3- b ]quinoline-6,8-dione derivatives with high yield of products in the presence of γ-Fe ₂ O ₃ @Zn-LDH@EAE-SO ₃ H as heterogeneous nanostructured catalyst.

The synthesized Fe₃O₄@WO₃-E-SMTU-Ni^II represents a significant contribution in the field of heterogeneous nanocatalysts for C–C coupling reactions in green media.

Dithioacetalization, as a well-known class of organic transformation, was carried out for protection of a wide variety of aromatic (with electron releasing and electron withdrawing substituents), heteroaromatic and aliphatic aldehydes as well as ketones by 1,2-ethanedithiol/or 1,3-propanedithiol in the presence of Fe₃O₄@MCM-41-GPTMS-Gu-Cu^IINPs. The corresponding 1,3-dithiolanes and 1,3-dithianes were obtained chemoselectively in the presence of Fe₃O₄@MCM-41-GPTMS-Gu-Cu^IINPs with hexagonal core-shell structure, superparamagnetic behavior, and average particle size of 8–25 nm under mild reaction conditions. The nanostructured catalyst could be separated easily from the reaction mixture using a magnetic bar and reused in several reaction runs without any remarkable reduction in its catalytic activity. Nearly neutral conditions, good to high yields of the products, operational simplicity, easy work-up procedure, compatibility with various functional groups make the present method valuable in addition to the known methodologies.

Expanded Perlite-Polyphosphoric Acid (EP-PPA) as a solid acid catalyst reported earlier by our group, has been found to be very effective for direct transformation of aldehydes into nitriles. The aforesaid catalyst exhibited excellent catalytic activ...

Herein a prominent, efficient, facile and environmentally benign catalytic activity of γ-Fe₂O₃/talc/Cu^II NPs (as a superparamagnetic composite with average diameter of about 20-30 nm) has been shown in C–S cross-coupling reactions. A wide variety of aryl iodides, aryl bromides and aryl chlorides with electron-donating or electron-withdrawing substituents reacted with S₈ or thiourea forming the corresponding substituted diphenyl sulfides under eco-friendly and mild process conditions. The results demonstrated remarkable catalytic activity of the nanostructured catalyst such as chemoselectivity and functional group tolerance. γ-Fe₂O₃/talc/Cu^II NPs as a magnetic catalyst was stable under reaction conditions and can be recycled at least five times with minimal loss of catalytic activity. Moreover, the use of commercially available and chemically stable sulfur transfer agent, eco-friendly and low-cost solvent and base as well as operational simplicity and easier work-up procedure make this method a promising candidate for potential applications in some organic reactions.
