On December 31, 2021, Zhang, Guoxiang; Zhang, Zongnan; Zeng, Rong published an article.Name: 4-Chloro-2-fluorotoluene The title of the article was Photoinduced FeCl3-Catalyzed Alkyl Aromatics Oxidation toward Degradation of Polystyrene at Room Temperature. And the article contained the following:

Main observation and conclusion : While polystyrene is widely used in daily life as a synthetic plastic, the subsequently selective degradation is still very challenging and highly required. Herein, we disclose a highly practical and selective reaction for the catalytically efficient oxidation of alkyl aromatics (including 1°, 2°, and 3° alkyl aromatics) to carboxylic acids. While dioxygen was used as the sole terminal oxidant, this protocol was catalyzed by the inexpensive and readily available ferric compound (FeCl3) with irradiation of visible light (blue LEDs) under only 1 atm of O2 at room temperature This system could further facilitate the selective degradation of polystyrene to benzoic acid, providing an important and practical tool to generate high-value chem. from abundant polystyrene wastes. The experimental process involved the reaction of 4-Chloro-2-fluorotoluene(cas: 452-75-5).Name: 4-Chloro-2-fluorotoluene

And the article contained the following:

Bis-2-(5-phenylacetamido-1,2,4-thiadiazol-2-yl)ethyl sulfide (BPTES) is a potent and selective allosteric inhibitor of kidney-type glutaminase (GLS) that has served as a mol. probe to determine the therapeutic potential of GLS inhibition. In an attempt to identify more potent GLS inhibitors with improved drug-like mol. properties, a series of BPTES analogs were synthesized and evaluated. The structure-activity relationship (SAR) studies revealed that some truncated analogs retained the potency of BPTES, presenting an opportunity to improve its aqueous solubility The analog I exhibited similar potency and better solubility relative to BPTES and attenuated the growth of P493 human lymphoma B cells in vitro as well as in a mouse xenograft model. The experimental process involved the reaction of Methyl 6-chloro-6-oxohexanoate(cas: 35444-44-1).Electric Literature of 35444-44-1
