Substituent effects on the stretching vibration of C═N in multi-substituted benzylideneanilines

Forty-nine samples of 3,4′/4,3′/3,3′-disubstituted benzylideneanilines (XBAYs) and 52 samples of multi-substituted XBAYs were synthesized, and their infrared absorption spectra were recorded in this paper. On the basis of the stretching vibration frequencies νC═N of C═N bridging bond of 158 samples of substituted XBAYs (including 57 samples of 4,4′-disubstituted XBAYs from reference and 101 samples of substituted XBAYs synthesized in this paper), an extensional research of substituent effects on the νC═N values from 4,4′-disubstituted XBAYs to multi-substituted XBAYs was made. A modified equation for quantifying the νC═N values of multi-substituted XBAYs was obtained (shown as Equation (3)). Equation (3) indicates that the excited-state substituent constant of Y and the substituent specific cross-interaction effect between X and X cannot be ignored for the quantitative regression analysis of the νC═N values of multi-substituted XBAYs. Compared with Equation (1), Equation (3) has a wider application and more accuracy in quantifying the νC═N values of substituted XBAYs.

Comparison of the substituent effects on the 13C NMR with the 1H NMR chemical shifts of CH=N in substituted benzylideneanilines

Fifty-two samples of substituted benzylideneanilines XPhCH=NPhYs (XBAYs) were synthesized, and their NMR spectra were determined in this paper. Together with the NMR data of other 77 samples of XBAYs quoted from literatures, the 1H NMR chemical

Visible-light-responsive multielectron redox catalysis of lacunary polyoxometalates induced by substrate coordination to their lacuna

We describe herein the efficient visible-light-responsive polyoxometalate-based multielectron photoredox catalysis induced by in situ coordination of alcohols to the lacuna of TBA4H4[γ-SiW10O36] (I, TBA=tetra-n-butylammonium). The coordination of alcohols to the lacuna of I generated a new highest occupied molecular orbital as the electron donor level and enabled the visible-lightresponsive multielectron transfer from alcohols to I, which could be utilized for aerobic alcohol oxidation and onepot synthesis of N-arylimines starting from nitroarenes and primary alcohols.

An attempt of molecular design and synthesis of 3,4′/4,3′-disubstituted benzylideneanilines with specified UV-Vis absorption maximum wavelength

Thirty-one samples of 3,4′/4,3′-disubstituted benzylideneanilines (XBAY) with specified UV-Vis absorption maximum wavelength (λmax) were designed and synthesized by applying the equation (Eqn (1)) which was abstracted from the UV-Vis absorption

Schiff bases of toluidines: Synthesis and effect of position of methyl group on biological potential

Condensation of 2-toluidine and 3-toluidine with benzaldebyde and substituted benzaldehydes (1-8) resulted in the formation benzal-2-toluidines (1a-Sa) and benzal-3-toluidines (1b-8b) respectively. The products were identified on the basis of elemental analysis and spectral studies and screened in vitro for their antifungal potential against three phytopathogenic fungi and two nematodes.

Synthesis of substituted oxindoles from α-chloroacetanilides via palladium-catalyzed C - H functionalization

A novel method for the synthesis of oxindoles is described. In the presence of catalytic palladium acetate and 2-(di-tert-butylphosphino)biphenyl, α-chloroacetanilides are converted to oxindoles in good to excellent yields with high functional group compatibility using triethylamine as a stoichiometric base. The cyclization is highly regioselective, obviating the need for prefunctionalized arenes. Plausible mechanistic pathways for the reaction are discussed. Copyright

Thorium(IV) halides form a number of complexes with the aromatic Schiff bases derived by condensation of anisaldehyde with aniline, 3-methyl, 4-methyl, 4-methoxy and 4-chloro aniline.The isolated complexes have the general composition ThX4 * 2L (X = Cl or

Complexes of Tin(II) Chloride With Aromatic Schiff Bases

Coordinative interaction of tin(II) chloride with some schiff bases derived from salicylaldehyde or anisaldehyde and substituted anilines has been studied.The newly synthesized molecular adducts of 1:1 stoichiometry have been characterized through elemental analysis, and spectroscopic data.A positive shift of the ν(C=N) mode in the infrared spectra of the complexes indicates that the bases act as neutral monodentate ligands coordinating only through their azomethine nitrogen atom.
