4-Hydroxybenzoic Acid-Based Hydrazide–Hydrazones as Potent Growth Inhibition Agents of Laccase-Producing Phytopathogenic Fungi That Are Useful in the Protection of Oilseed Crops

Molecules
The research on new compounds against plant pathogens is still socially and economically important. It results from the increasing resistance of pests to plant protection products and the need to maintain high yields of crops, particularly oilseed crops ...

Degradation of chlorinated benzaldehydes in aqueous solutions by UV-irradiation

International Journal of Photoenergy, 2002
Photoinduced degradation of chlorinated benzaldehydes was investigated using UV light with λ = 253.7 nm in aerated aqueous solutions. Substrate degradation rate as expressed by first order reaction kinetics revealed rate constants, k; 7.45×10−3 min-1, 3 ...

Synthesis and Characterization of Chiral Nitrobenzaldehyde - Schiff Base Ligands

Molecules, 2003
Three chiral nitrobenzaldehyde/Schiff base ligands (2a-c) were prepared by the reaction of ortho, meta, and para-NO2 substituted benzaldehydes (1a-c) with (1R,2R)-(-)-1,2-diaminocyclohexane. The structures of ligands 2a-c were characterized by IR, 1H-NMR,

Large acceleration under highly concentrated conditions: Synthesis of chalcones using a small amount of DMF or [emim]N(CN)2

Results in Chemistry, 2022
A variety of chalcones were synthesized by the reactions between benzaldehydes and acetophenones catalyzed by Ba(OH)2. The reactions in the presence of a small amount of DMF or 1-ethyl-3-methylimidazolium dicyanamide ([emim]N(CN)2) were faster than those

Tyrosinase Inhibitor Activity of Coumarin-Resveratrol Hybrids [PDF]

, 2009
In the present work we report on the contribution of the coumarin moiety to tyrosinase inhibition. Coumarin-resveratrol hybrids 1-8 have been resynthesized to investigate the structure-activity relationships and the IC50 values of these compounds were

Benzaldehyde-Functionalized Polymer Vesicles [PDF]

ACS Nano, 2009
Polymer vesicles with diameters of ca. 100-600 nm and bearing benzaldehyde functionalities within the vesicular walls were constructed through self-assembly of an amphiphilic block copolymer PEO(45)-b-PVBA(26) in water. The reactivity of the benzaldehyde functionalities was verified by cross-linking the polymersomes and also by a one-pot cross-linking ...

1,3-Dipolar cycloadditions of azomethine imines [PDF]

, 2015
Azomethine imines are considered 1,3-dipoles of the aza-allyl type which are transient intermediates and should be generated in situ but can also be stable and isolable compounds.

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

Advanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.
