N-(4-carboxyphenyl) anthranilic acid (compound 31)
A mixture of 2-chlorobenzoic acid (1 mmol), 4-aminobenzoic acid (1 mmol), K2CO3 (2 mmol), Cu powder (0.009 mmol), and Cu2O (0.009 mmol) in 0.3 mL of 2-ethoxyethanol was refluxed at 130°C under inert...
Well written paper. The technique of using a removabile filler to direct pore size in a membrane is an innovative method and should be studied more.
The paper presents an innovative way to synthesis bi functional linker (in this case azido-amine linkers). The method used described as concurrent reaction-extraction taking place in one pot has attracted a lot of attention. In the synthesis of compound 1 a...
Summary:
An efficient and environmentally benign method for synthesis of 1,2-disubstituted and 2 substituted benzimidazoles has been described. Although previous methods are available in literature for synthesis of such compounds, the ease of operation,...
Summary:
A polymeric film as fluorescent sensor for detection of Pb2+ in aqueous solutions, synthesised from 1-vinylimidazole, poly(ethylene glycol) diacrylate and trimethylolpropane triacrylate has been described. The manuscript also describes the...
Summary:
This article describes a method for cyclic olefin polymerization employing a non-chelated monodentate benzimidazole Ni(II) complex. The specific reaction catalysed, is the vinyl polymerization of norbornene. The article also describes the methods...
Summary:
This paper describes a novel method for efficient synthesis of amides through reaction of carboxylic acids with amines by activation with P(OEt)3 and Iodine. The novelty lies in easy amidation of several primary and secondary amines to synthesize...
Summary:
This paper reports the synthesis of hexamethylenebisacetamide (HMBA) without organic solvent or gas protection via amide exchange reaction of hexamethylenediamine (HDA) with CH3CN and H2O catalysed by CuO. The authors report the method to be more...
Summary:
This paper reports the reactivity of the methylene group of 1-naphthyl-2-cyanoacetamide 1 which was tested towards different reagents. These new compounds have been reported to be characterized by elemental analysis, IR, 1HNMR, 13C NMR, and mass...
Summary:
This research article reports a study on the thermocehemical behaviour of halogen-containing molecules in atmospheric chemical processes. The thermodynamic and thermochemical model of these components helps in understanding the interactions in...
In this paper, selective bromination of perylene diimides is described. I was able to reproduce the bromination of 1a. However, the workup involves evaporating large volumes of bromine. I was able to isolate similar yields of products by quenching the...
Summary:
This paper describes the synthesis of three iso-structural Zn(II), Cd(II), and Hg(II) complexes with 1-benzyl-2-phenyl-1H-benzimidazole (BPB). Single crystal X-ray determination of CdBPB and HgBPB were done along with Structural analysis of ZnBPB...
Summary:
This paper reports the binding effect of some novel benzimidazole derivatives with Cu2+ metal ion by solution spectral studies. Benzimidazole complexes (1 – 6) were studied for fluorescence quenching by Cu2+ in comparison to Fe3+, Mg2+, Ag+, K+...
Summary:
This paper reports the synthesis of a new class of acrylamide thioglycoside derivatives utilizing a one-pot synthesis. Further heating of the resultant glycosides with hydrazine is reported to give pyrazole derivatives. Among those synthesized,...
Summary: The paper discusses the synthesis, reactivity and stability of α-lithio N,N dimethylacetamide.
The paper described carefully the use of various solvents (pentane, THF) and their impact on the formation of the desired product.
It also described...
Summary
The article describes the synthesis of cyclen based chelators which can accommodate and stabilize di-and trivalent metal ions for biomedical applications. The chelators were synthesized first by monoalkylating cyclen (1,4,7,10...
The procedure described in this paper is very reliable. The ozone should be used in a fully functional fume hood as described.
1. Synthesized 10.1 g of crude diphenaldehyde starting from 10.0 g of phenanthrene.
2. The crude 1H-NMR of product is 80%...
Summary:
A new copper selective solid-state electrode based on o-xylylenebis(N,N-diisobutyldithiocarbamate) ionophore has been described. It has been developed for selectively measuring the copper levels found in the tea infusion samples. Robust, cheap...
Summary:
This paper describes the theoretical study on borazine and substituted borazines by the means of density functional theory. Amino group was used as the common donor group while four acceptor groups namely –NO2, –C≡N, –COCl and –NMe2 were chosen...
Summary:
A convenient, clean and environmentally benign method for ‘‘on water’’ synthesis of benzothiazoles/benzothiazolines has been described. Although previous methods are available in literature for synthesis of such compounds, the ease of operation,...
