Good study - need to find methods for iodinated-molecules

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...

Good experimental, some modification to work-up

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...

Reproducible but very routine work

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...

Many details omitted which makes it clumsy to repeat

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⁺...

Innovative approach - Lower yields

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,...

Extremely helpful and reliable paper

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...

Reliable Procedure

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%...

Should include Mn & Al data for clarity

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...

Good theory. Experimental data can add value.

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...

Excellent practical method. Highly recommended.

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,...
