Study on a polyacrylate-based waterborne coating: facile preparation, convenient self-healing behavior and photoluminescence properties

This paper describes the preparation of a series of 16 anthranilic acids in yields ranging from 51 to 97%, by treating the isatins with NaOH and H2O2. Independently of the nature of the substituent on the aromatic ring, the reactions were complete in 15 min at room temperature, whereas those of isatins containing a substituent on the nitrogen atom required longer reaction time for completion (45 min) under the same reaction conditions.

Abstract TiO2 nanoparticles in the brookite phase were synthesized within an environmentally friendly method by magnetized water obtained by the US-patent magnetizing device (US10507450B2), which changes the properties of all types of the solvents with no limitation (protic or aprotic). Furthermore, this study is the first report on the synthesis of brookite TiO2 nanoparticle through magnetized water at room temperature. The procedure was tested by five different water; ordinary, 15, 30, 45, and 60min-magnetized water. The products were analyzed by various techniques including XRD, FESEM, ICP, BJH-plot, t-plot, Langmuir plot, BET, TEM, and FTIR. The result showed that the products obtained from 30 min-magnetized water were the most properly indexed TiO2 brookite phase with high surface activity. This sample could be a suitable green photocatalyst.

Abstract This study describes the formation of new C-C bonds through the allylation reaction of different aldehydes promoted by beta zeolite. This environmentally friendly method was characterized by its efficiency, versatility, and chemoselectivity in the formation of different homoallylic alcohols. Homoallylic alcohols were obtained in good yields (80% to 96%), short reaction times (30 to 75 min) at room temperature, and without the need for additional purifications. In addition, water was used as a co-solvent, ensuring the method a development in the field of green chemistry. Moreover, it was found that the zeolite beta can be reused for up to one reaction cycle without loss of its efficiency.

AbstractDevelopment of practical deuteration reactions is highly valuable for organic synthesis, analytic chemistry and pharmaceutic chemistry. Deuterodehalogenation of organic chlorides tends to be an attractive strategy but remains a challenging task. We here develop a photocatalytic system consisting of an aryl-amine photocatalyst and a disulfide co-catalyst in the presence of sodium formate as an electron and hydrogen donor. Accordingly, many aryl chlorides, alkyl chlorides, and other halides are converted to deuterated products at room temperature in air (>90 examples, up to 99% D-incorporation). The mechanistic studies reveal that the aryl amine serves as reducing photoredox catalyst to initiate cleavage of the C-Cl bond, at the same time as energy transfer catalyst to induce homolysis of the disulfide for consequent deuterium transfer process. This economic and environmentally-friendly method can be used for site-selective D-labeling of a number of bioactive molecules and direct H/D exchange of some drug molecules.
