Adsorption and Diffusion Characteristics of 2-Naphthol from Aqueous Media by Chitosan-ENR Biocomposites

open access: yesASEAN Journal on Science and Technology for Development, 2018
Chitosan entrapped ENR-50 (CTS-t-ENR) biocomposites developed were studiedfor the absorption and desorption of 2-naphthol in aqueous media. Biocomposites comprising chitosan (CTS) immobilized or trapped in a partially crosslinked ENR (designated as CTS-t-

Nucleophilic Reactions of Cyclobutenones and the Related 4,4‐Dichlorocyclobutenone Derivatives

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cyclobutenone derivates and their 4,4‐dichloro counterparts have an uninterrupted attention as useful synthons in the synthesis of complex organic molecules. Their nucleophilic reactions remain underexplored. This review brings attention to these reactions, whose outcome is not straightforward.

Preparation of 5-Bromo-2-naphthol: The Use of a Sulfonic Acid as a Protecting and Activating Group

open access: yesMolbank, 2009
The preparation of 5-bromo-2-naphthol (4) in three steps from 5-amino-2-naphthol (1) is described. A sulfonic acid group is introduced at the 1-position as an activating and protecting group for the Sandmeyer reaction.

Resolution of BIS-2-Naphthol Sulfone Via Diastereomeric Phosphates [PDF]

open access: yes, 2004
The resolution of bis-2-naphthol sulfone is the goal of this research. In a manner similar to that of other resolved diols such as bi-2-naphthol and bis-2-naphthol sulfide, it was proposed that bis-2-naphthol sulfone might also be resolved.

Leveraging Isomerization of Azo Dyes and Imines for the Facile Synthesis of Oxadiazepines and Related Heterocycles

open access: yesJournal of Heterocyclic Chemistry, EarlyView.
A robust method for synthesizing substituted oxadiazepines and related heterocycles via intramolecular SNAr is detailed. Under mild conditions, this methodology has been leveraged to afford products of varying electronic and aryl nature in up to 99% yields.

Silicon differentially protects PSII and PSI photochemistry and preserves fatty acid metabolism in salt‐stressed Sorghum bicolor (L.)

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Silicon (Si) has been demonstrated to be an important element to enhance crop tolerance against salinity. Nevertheless, mechanisms underlying Si's mitigation of salt stress remains insufficiently explored and understood. This study aims to provide new insights into Si's impact on salt‐stressed Sorghum bicolor (L.) supplied or not ...
