Experimental Study of Free Energy of Activation of Flow and Grunberg-Nissan Parameters in Binary Liquid Mixtures

open access: yesBibechana, 2010
The binary mixtures of cabontetrachloride with isobutylmethylketone and benzaldehyde were studied at 308.15 by measuring viscosities and densities. The derived and excess viscosities, activation energy of flow and Grunberg-Nissan parameters have been ...

Analysis of Benzaldehyde Interactions with Nucleosides

open access: yes, 2012
Benzaldehyde is present in many commonly consumed foods (ex: coffee, cherries, almonds, and apricots). In addition to its low toxicity, benzaldehyde has been reported to demonstrate anticancer activity.

Profiling ephedrine/pseudoephedrine and methamphetamine synthesised from benzaldehyde, nitroethane and dimethyl carbonate

open access: yes
In previous work, a novel pathway for the synthesis of ephedrine/pseudoephedrine and methamphetamine using the precursors benzaldehyde, nitroethane and dimethyl carbonate was investigated, and an impurity profile presented. This paper presents chiral and

Conformational Studies of ortho-Substituted Benzaldehyde Chromium Tricarbonyl Complexes

open access: yes, 2003
The syn/anti conformational equilibrium of o-substituted benzaldehyde chromium tricarbonyl complexes was studied by CD and 1H NMR (NOE). The preferred conformation of the o-methyl-, o-methoxy-, and o-iodobenzaldehyde complexes is anti, while those of the

(2‐Phosphinophenyl)aluminum Dichloride Complexes as Intramolecular Al/P Frustrated Lewis Pairs for Ketone, Ester, and Imine Activation

open access: yesChemistry – A European Journal, EarlyView.
Three 2‐phosphinophenylaluminum dichloride complexes were synthesized and characterized as novel intramolecular FLPs. These FLP systems exhibit high Lewis acidity and effectively activate challenging substrates including aliphatic ketones, imines, and esters. DFT analysis revealed that strain release and Al–P dynamics govern their reactivity. Abstract (

The One‐Step Synthesis of Biologically Active Isochromans from Lignin‐Derived Aromatic Monomers in Tunable Deep Eutectic Solvents

open access: yesChemistry – A European Journal, EarlyView.
A straightforward one‐step protocol enables the synthesis of bio‐based and biologically active isochromans through the Oxa‐Pictet cyclization involving diverse aldehydes, including vanillin in combination with lignin‐derivable homovanillyl alcohol, a prominent aromatic platform chemical obtainable via diol‐assisted fractionation of lignocellulose ...

Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis

open access: yesChemistry – A European Journal, EarlyView.
We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.
