Synthesis, structural characterisation and electronic behaviour of iron(II) and nickel(II) complexes of N,N-bis(2-pyridylmethyl)aniline Ni(II) and Fe(II) complexes of the new ligand N,N-bis(2-pyridylmethyl)aniline (phdpa) of the general formula [M(phdpa) 2](ClO 4) 2 have been ...
A short and simple synthesis of tetrahydropyrimidine derivatives were accomplished in good to excellect yields at room temperature by the reaction of dimethylacetalynedicarboxylate, aniline, and formaldehyde in the presence of 5 mol% of molecular iodine at room temperature in ethanol for 5 min.关键...
12. The molar mass of aniline is 93 g/mol. What is its molecular formula? 13. Calculate the mass percent of carbon, nitrogen and oxygen in acetamide, C 2 H 5 NO. 14. A 50.51 g sample of a compound made from phosphorus and chlorine is decomposed. Analysis of the products showed that...
The weight of ideal UiO-66 at 350 °C is 220.2% which agrees with the chemical formula of Zr6O6(BDC)6, In contrast, the weight of defective UiO-66 at 350 °C is below 220.2% suggesting the deficiency of BDC linkers. The defective UiO-66 takes the formula of Zr6O6+x(BDC)6-...

Conclusion In the QSAR model, the molecular descriptors of MATS8s, Chi4, bcutv8, Petitjeant and fr_aniline were highly influenced the antitubercular activity. The developed QSAR model helps to predict the antitubercular activity of tetrahydronaphthalene derivatives.Similar...
(d,p) basis set. Frequency analysis was performed to guarantee that all the structures were the minimum points on the potential energy surface. Calculation of oxidation potential were performed under an implicit solvation model with dielectric properties of Aniline (dielectric constant = 7.3). ...
The hyperpolarizability of this molecule is much bigger than that which could be deduced by combining results for nitrobenzene and aniline (see Table 1). This enhancement of the second-order nonlinearity is generally interpreted in terms of internal charge transfer in a molecule containing both ...
2a, iii). Also note that symmetric azoxy compound shows two peaks with different UV/vis spectra according to HPLC, due to the spontaneous mutual E/Z isomerization of the N = N bond1,5). Given that 1 had mutual C4 E/Z isomerization and that 3′ had the same molecular formula as...
(2) was treated with various substituted anilines for 5–8 h in the presence of toluene andp-toluene sulfonic acid as a catalyst to give Schiff bases(3a-g). The target compounds4a-gand5a-dwere synthesized by the reaction of intermediates3a-gwith thiolactic acid and thioglycolic acid by ...
