Two N2O2-donor macrocyclic Schiff bases mD1 and mD2 (mD1 = 1,5-diaza-2,4:7,8:16,17-tribenzo-9,15-dioxa-cyclooctadeca-1,5-dien; mD2 = 1,5-diaza-2,4:7,8:15,16-tribenzo-9,14-dioxa-cycloheptadeca-1,5-dien) were prepared by the [1+1] cycl

In this work, [1 + 1] macrocyclic Copper(II) Schiff base complex ([CuL](NO3)2.H2O) was synthesized and grafted on reduced graphene oxide successfully. The novel prepared sample was characterized by physico-chemical techniques and used as a photocatalyst for the reduction of nitroaromatic compounds to their amine derivatives at room temperature under visible-light irradiation with hydrazine mono hydrate. From the prepared samples, reduced graphene oxide loaded with 30% [CuL](NO3)2.H2O catalyst (rGO/CuM30) shows the best efficiency for converting different nitroaromatic compounds to the corresponding amino compounds using visible light. As-prepared catalyst illustrated excellent activity for the reduction of 2-nitrophenol to 2-aminophenol (100% conversion) in only 90 min. Finally, the catalyst could be recovered for five times and reused without decreasing of its efficiency.

In this work, the new trinuclear manganese catalyst defined as Fe3O4@NFC@NNSM-Mn(iii) was successfully manufactured and fully characterized by different techniques, including FT-IR, XRD, TEM, SEM, EDX, VSM, and ICP analysis. There have been reports of the use of magnetic catalysts for the synthesis of xanthine derivatives. The critical potential interest in the present method include short reaction time, high yields, recyclability of the catalyst, easy workup, and the ability to sustain a variety of functional groups, which give economical as well as ecological rewards. Also, the synthesized catalyst was used as a recyclable trinuclear catalyst in alcohol oxidation reactions at 40 °C. The magnetic catalyst activity of Fe3O4@NFC@NNSM-Mn(iii) could be attributed to the synergistic effects of the catalyst Fe3O4@NFC@NNS-Mn(iii) with melamine. Employing a sustainable and safe low temperature, using an eco-friendly solvent, no need to use any additive, and long-term stability and magnetic recyclability of the catalyst for at least six successive runs are the advantages of the current protocol towards green chemistry. This protocol is a benign, environmentally friendly method for heterocycle synthesis. This journal is

Design and synthesis of a new class of 2,4-thiazolidinedione based macrocycles suitable for Fe3+ sensing
Sepay, Nayim,Mallik, Sumitava,Saha, Pranab C.,Mallik, Asok K.
, p. 15270 - 15276 (2018/09/29)
A new class of three 2,4-thiazolidinedione based macrocycles (3a-c) have been synthesized and then characterized from spectral data and X-ray crystallography. The fluorescence quenching of the compounds caused by the addition of nineteen separate metal cations to their solutions in ethanol-water (3 : 1) was investigated, when it was observed that among the cations, the response to Fe3+ was distinctive. Again, among the macrocycles, 3c gave the best result.
