As th electronegativity of the R-groups on the catalyst increases, yields tended to drop below reported values. While annoying, the purity of the finale compound was excellent.
On a more positive note, the route proposed in this publication can be easily...
Response letter from reader suggesting their is now clinical evidence for salicylates casuing GI mucosa erosion and eventual bleeding.
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,...
This paper by Erlanson and colleagues describes the disulfide tethering technique, which has proven to be a reproducible and versatile method for finding fragment hits. The main advance is the covalent targeting of the fragment library to a specific site on a...
A detailed observational study of the trends in biological sciences publishing, including analysis of time-to-publication, time-to-graduation, and the increasing minimum publication unit. The paper is interwoven with thoughtful analysis and perspective from...
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,...
Summary:
This paper reports a CTAB-catalyzed method developed for the synthesis of 2-substituted benzothiazoles by the condensation of 2-aminothiophenol with aldehydes (RCHO: R = Alkyl, Aryl, Heteroaryl, 2-Arylformyl). Use of cetyltrimethyl ammonium...
Toomey and colleagues report the results of a survey of 14 early career researchers (ECRs) about "open science". On a whole, these ECRs view open science positively, but hold reservations about the impact adopting open science practices might have on their...
