Deoxydichlorination of aldehydes catalyzed by Diphenyl sulfoxide
Chimica Techno Acta, 2021 The diphenyl sulfoxide-catalyzed conversion of aldehydes to 1,1-dichlorides is reported. The reaction proceeds via a sulfurous (IV)-catalysis manifold in which diphenyl sulfoxide turnover is achieved using oxalyl chloride as a consumable reagent.

Some Chemical Aspects of 1,2,4-triazine derivatives [PDF]
Delta Journal of Science, 2016 Condensation of 3a,b with some aromatic aldehydes afforded the Schiff bases (4a-f). Reaction of 3a,b witharomatic aldehydes and alkyl phosphites gave the corresponding amino phosphonates (5a-d). Heating 3a,b with 6a-f in POCl3 at85 °C furnished the amino

Molecular Response to Toxic Diatom-Derived Aldehydes in the Sea Urchin Paracentrotus lividus
Marine Drugs, 2014 Diatoms are dominant photosynthetic organisms in the world’s oceans and represent a major food source for zooplankton and benthic filter-feeders. However, their beneficial role in sustaining marine food webs has been challenged after the discovery that ...

Oxidation of Aldehydes Used as Food Additives by Peroxynitrite
Antioxidants, 2023 Benzaldehyde and its derivatives are used as food supplements. These substances can be used mainly as flavorings or as antioxidants. Besides, peroxynitrite, an oxidizing agent, could be formed in canned food. Both species could react between them.
