Thermodynamics Evaluation of Selective Hydride Reduction for α,β-Unsaturated Carbonyl Compounds [PDF]

open access: yesMolecules, 2023
The selective reduction of α,β-unsaturated carbonyl compounds is one of the core reactions and also a difficult task for organic synthesis. We have been attempting to study the thermodynamic data of these compounds to create a theoretical basis for ...

Assessing Impacts of Additives on Particulate Matter and Volatile Organic Compounds Produced from the Grilling of Meat

open access: yesFoods, 2022
Cooking fumes are an important source of volatile organic compounds (VOCs), particulate matter (PM), and carbonyl compounds. The additive is wildly applied in grilling meat for flavor improvement.

Research Progress of Active Carbonyl Compounds Produced by Oxidantion of Fats in Food

open access: yesShipin gongye ke-ji, 2022
During food processing, reactive carbonyl compounds (RCCs) are produced due to the oxidation of fatty acids. Since RCCs are closely related to inflammation, aging, tumor, Alzheimer's disease, etc., they have attracted extensive attention in the field of ...

Characterisation and optimisation of a sample preparation method for the detection and quantification of atmospherically relevant carbonyl compounds in aqueous medium [PDF]

open access: yesAtmospheric Measurement Techniques, 2015
Carbonyl compounds are ubiquitous in the atmosphere and either emitted primarily from anthropogenic and biogenic sources or they are produced secondarily from the oxidation of volatile organic compounds.

Zn(BH4)2/Al2O3: A new synthetic method for efficient and convenient reduction of organic carbonyl compounds to their corresponding alcohols [PDF]

open access: yesJournal of the Serbian Chemical Society, 2013
Zn(BH4)2 (0.5-2 mmol) in the presence of Al2O3 (1 mmol) reduces varieties of organic carbonyl compounds such as aldehydes, ketones, acyloins, α-diketones and α, β-unsaturated carbonyl compounds to their corresponding alcohols. Reduction reactions were
