General description

Salicylaldehyde is the main odor constituent of buckwheat flour. It is also found in anise and vanilla extracts.

Application

  • Facile synthesis of iminated lignin for enhanced free radical and lead ion scavenging capabilities.: This study presents a novel method for synthesizing iminated lignin using salicylaldehyde. The modified lignin demonstrates significantly improved free radical and lead ion scavenging abilities, highlighting its potential application in environmental remediation and biochemical processes (Xia et al., 2024).

The gold(I)/chiral Brønsted acid relay catalysis enabled a highly stereoselective three-component reaction of salicylaldehydes, anilines, and alkynols to give aromatic spiroacetals in high yields and stereoselectivities.

We synthesized two constitutionally isomeric bis(iminomethyl)-2,6-dihydroxynaphthalenes, namely, α,α-diimines 1 and β,β-diimines 2, which can be formally represented as fused salicylaldimines with resonance-assisted hydrogen-bonding sites. Spectroscopic data show that the OH/OH, NH/OH, and NH/NH forms of 1 were in equilibrium in

A new dinuclear copper salicylaldehyde-glycine Schiff-base complex [Cu(2)(Sal-Gly)(2)(H(2)O)(2)] was synthesized and structurally characterized. [Cu(2)(Sal-Gly)(2)(H(2)O)(2)] crystallized in the monoclinic system in the P2(1)/c space group. The molecule is a dinuclear complex, formed by two [Cu(Sal-Gly)(H(2)O)] units.
