Copper-Promoted Trifluoromethanesulfonylation and Trifluoromethylation of Arenediazonium Tetrafluoroborates with NaSO2CF3

A tunable chemoselective trifluoromethanesulfonylation and trifluoromethylation of arenediazonium tetrafluoroborates with Langlois’ reagent (NaSO2CF3) was developed. The Cu2O-catalyzed reaction in DMSO gave aryl trifluoromethanesulfones as the major products. On the other hand, the trifluoromethylated arenes were produced in the presence of oxidant tert-butyl hydroperoxide, CuBF4(MeCN)4, and 2,2?;6?,2 terpyridine (tpy). Both of these transformations proceed under mild conditions and tolerate functional groups.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 57319-65-0 is helpful to your research. 57319-65-0

Dehydrative Cp?Co(III)-Catalyzed C-H Bond Allenylation

An efficient, unprecedented reactivity of Cp?Co(III) for the synthesis of tetrasubstituted allenes under mild conditions is disclosed. Electron-rich and highly nucleophilic cobalt facilitates the dehydrative C-H bond allenylation directly from propargylic alcohols without any derivatization. The reaction proceeds via reversible cyclometalation followed by alcohol-directed regioselective alkyne insertion and beta-hydroxy elimination to provide the tetrasubstituted allenes.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 54109-03-4

Synthesis of new furan polycycles via photochemical reaction in neutral and acidic medium

New furan derivatives of o-divinylbenzenes were synthesized and their photochemical reactivity has been investigated in neutral and acidic medium. Depending of the structure of the starting materials and pH value, the new cyclization (11, 16, 20), cycloaddiotion (12, 13, endo-17, exo-18), electrocyclization (21, 22) and dimeric (15, 19) products were isolated. While photochemical investigation in neutral medium showed that the main intramolecular process is cycloaddition, in the case of acidic photochemistry, due to the protonation of the starting molecule, electrocyclization process comes to expression and formation of dihydronaphtalene products 21 and 22.

Synthesis, characterization, biological activity, and 3D-QSAR studies on some novel class of pyrrole derivatives as antitubercular agents

A new series of pyrrole derivatives have been designed, synthesized, and their structures have been elucidated along with the evaluation of antitubercular activity against Mycobacterium tuberculosis H37Rv using the microplate alamar blue assay method and antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumoniae, and Escherichia coli by broth micro-dilution assay method. Structural activity relationships and 3D-QSAR analysis have been carried out by Topomer Comparative Molecular Field Analysis (CoMFA). Training set of 42 and test set of 8 active compounds were used to develop the method that showed cross-validated correlation coefficient (q 2) of 0.815, standard error of prediction of 0.36, non-cross-validated correlation coefficient (r 2) of 0.973, and standard error of estimate of 0.14 with six components.

Pyrolysis of poplar wood sawdust by TG-FTIR and Py-GC/MS

Pyrolysis of certain poplar wood sawdust (PWS) was studied by thermogravimetric analyzer coupled with Fourier transform infrared spectroscopy (TG-FTIR). Different heating rates were applied with final temperature of 950 C and about 80% loss weight was observed at the heating rate of 20-80 C/min. The temperature trend of evolving gaseous products of PWS was also investigated. Following experimental research on pyrolysis of PWS was carried out on a pyrolysis-gas-chromatography/mass spectrometry (Py-GC/MS). Associated with the analysis results of TG-FTIR and Py-GC/MS for the pyrolytic products, PWS undergoes in three consecutive stages, corresponding to (1) moisture evaporation, (2) thermal decomposition, and (3) further carbonization. The main pyrolysis sections and the maximum weight loss rates are similar for different heating rates. Carbonyls, including aldehydes and ketones, are the main volatile products, in addition to phenols, furans, benzenes, acids, and so on. As the main gaseous products, CO, CO2, CH4 are released out greatly. Furthermore, possible pyrolysis mechanisms of cellulose, hemicellulose and lignin in biomass including PWS were also proposed. All of the results and findings would help further understanding of thermal behavior of PWS and its thermo-chemical utilization for fuels and chemicals.
