The solid-state hydrolysis and air calcination of aluminum-doped TiCl3 leads to crystalline anatase TiO2 that is stable on heating to 1000 degrees C, in contrast to control studies with related AlCl3 and TiCl3 physical mixtures that produce rutile TiO2 under the same conditions.

A synthesis of several carbapenem antibiotics including 9-methoxythienamycin is described. The final deprotection of C-3 esters was accomplished by a novel procedure using aluminum trichloride under a very mild condition. The antibacterial activity against Gram-positive and Gram-negative bacteria is shown.

Diglycolyl chlorides, commercially available or obtained from the corresponding dicarboxylic acids, have been converted into the corresponding diamides by reaction with a wide range of amines in an organic-aqueous biphasic system (Schotten–Baumann approach) in high yields. Treatment with poly(4-styrenesulfonic acid) afforded the pure compounds. Substituted diglycolyl diesters, obtained by coupl...

The authors have assessed the possibility of electrochemical synthesis a wide range reagents based on titanium trichloride as part work. Despite growing demand for and its derivatives, production technology this reagent has not been improved long period. Traditional technologies feature high environmental industrial hazards, process itself energy consumption complex hardware scheme. As prelimin...

The shorter distance between the bridging chlorine atoms compared with that between the aluminum atoms is discussed in terms of the sp hybrid model and the MCAS atomic model. Lewis Acids and their Dimers Boron and aluminum have just three (3) valence electrons and form trivalent molecules. Typical ones are BH3, BCl3 and AlCl3. The latter are Lewis acids (after G.N. Lewis 1 ); i.e., they lack an...

An efficient and practical procedure for the synthesis of esonarimod, (R,S)-2-acetylthiomethyl-4-(4-methylphenyl)-4-oxobutanoic acid (1), a new antirheumatic drug, has been developed. The intermediate, 2-methylene-4-(4-methylphenyl)-4-oxobutanoic acid (2), was prepared by Friedel-Crafts acylation of toluene with itaconic anhydride (3) in the presence of aluminum trichloride and nitrobenzene in ...

The purpose of this study is to quantify the polyphenolic content and evaluated anti-inflammatory antioxidant activity four plants extracts Annona senegalensis, Ipomoea batatas, Terminalia superba Psidium guajava. Phenolic flavonoid contents were determined by Folin-Ciocalteu aluminum trichloride methods, respectively with ethanolic extract. was accessed DPPH FRAP methods. results analysis indi...

The present study aimed to investigate the effects of intestinal endotoxemia (IETM) in a rat model of aluminum neurotoxicity established by D-galactose and aluminum trichloride (AlCl3). Adult Wistar rats were administered D‑galactose and AlCl3 to create the aluminum neurotoxicity model. The learning and memory abilities of the rats were subsequently observed using a Morris water maze test and t...

In a previous paper of this series (1) we have shown that while the dilution curve for cod liver oil with antimony trichloride is not a linear function, a comparison can be made between the colorimetric assay of vitamin A in certain fish oils, with a chloroform solution of antimony trichloride, and the biological assay upon the same oils, when certain precautions are taken. In a second paper (2...
