“…The linewidth is attributable to intramolecular and reticular water interactions. [30] Between 1700-1500 cm À 1 1-3 showed vibration bands associated to CÀ N stretching with changes in the lineshape for each compound. [31] For 1 two well defined signals were observed, 2 showed a band with a small shoulder around 1580 cm À 1 and 3 showed a broad band, which was fitted with two Gaussians (Figure 5).…”

Tautomeric equilibria at room temperature were studied for three aromatic imine polyol compounds, previously reported 2-((2-hydroxybenzylidene)amino)-2-(hydroxymethyl)propane-1,3diol 1 and two new compounds 2-(((1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl)imino)methyl)benzene-1,4-diol 2 and 3-(((1,3-dihydroxy-2-(hydroxymethyl)propan-2 yl)imino) methyl)benzene-1,2-diol 3. The dynamic behavior of these equilibria is described by a combination of IR, UV-Vis and NMR spectroscopic measurements with DFT and TDDFT calculations in condensed phase. Among the different approaches, the combination of UV-Vis experimental spectra with the oscillator strengths values estimated from TDDFT calculations allowed for the assessment of the tautomeric populations in DMSO and methanol. These results were consistent with different functionals employed GGA, Hybrid and MetaGGA.

“…Schiff-base-type silatranes ( 11 ) ( Figure 4 ) were obtained from APS and three derivatives of salicylaldehyde with 3,5-dichloro-, 3-methoxy-, and 3,5-di-tert-butyl- substituents [ 48 ]. The antifungal activity of these compounds was evaluated using three species of fungi ( Aspergillus fumigatus, Penicillium chrysogenum, Fusarium ).…”

3-Aminopropylsilatrane and Its Derivatives: A Variety of Applications

Silatranes arouse much research interest owing to their unique structure, unusual physical–chemical properties, and diverse biological activity. The application of some silatranes and their analogues has been discussed in several works. Meanwhile, a comprehensive review of the wide practical usage of silatranes is still absent in the literature. The ability of silatranes to mildly control hydrolysis allows them to form extremely stable and smooth siloxane monolayers almost on any surface. The high physiological activity of silatranes makes them prospective drug candidates. In the present review, based on the results of numerous previous studies, using the commercially available 3-aminopropylsilatrane and its hybrid derivatives, we have demonstrated the high potential of 1-organylsilatranes in various fields, including chemistry, biology, pharmaceuticals, medicine, agriculture, and industry. For example, these compounds can be employed as plant growth biostimulants, drugs, optical, catalytic, sorption, and special polymeric materials, as well as modern high-tech devices.

“…It can be attributed to fact that TMN has more electron donating group (naphthalene) attached to it so this increases the electron density on the ring and thus make the removal of electron hence oxidation more facile. Oxidation of TMC is difficult comparatively because Chloro (−Cl) group induces withdrawing character decreasing the electron density and thus oxidation is somewhat difficult [37].…”
