Upcycling of dynamic thiourea thermoset polymers by intrinsic chemical strengthening was written by Feng, Haijun;Zheng, Ning;Peng, Wenjun;Ni, Chujun;Song, Huijie;Zhao, Qian;Xie, Tao. And the article was included in Nature Communications in 2022.Quality Control of Isopropylisothiocyanate The following contents are mentioned in the article:

Thermoset polymers are indispensable but their environmental impact has been an ever-increasing concern given their typical intractability. Although concepts enabling their reprocessing have been demonstrated, their practical potential is limited by the deteriorated performance of the reprocessed materials. Here, we report a thiourea based thermoset elastomer that can be reprocessed with enhanced mech. properties. We reveal that the thiourea bonds are dynamic which leads to the reprocessibility. More importantly, they can undergo selective oxidation during high temperature reprocessing, resulting in significant chem. strengthening within certain reprocessing cycles. This is opposite to most polymers for which reprocessing typically results in material deterioration. The possibility of having materials with inherent reprocessing induced performance enhancement points to a promising direction towards polymer recycling. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Quality Control of Isopropylisothiocyanate).

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Quality Control of Isopropylisothiocyanate

5-Keto-3-cyano-2,4-diaminothiophenes as selective maternal embryonic leucine zipper kinase inhibitors was written by Boutard, Nicolas;Sabiniarz, Aleksandra;Czerwinska, Klaudia;Jarosz, Malgorzata;Cierpich, Anna;Kolasinska, Ewa;Wiklik, Katarzyna;Gluza, Karolina;Commandeur, Claude;Buda, Anna;Stasiowska, Agata;Bobowska, Aneta;Galek, Mariusz;Fabritius, Charles-Henry;Bugaj, Marta;Palacz, Edyta;Mazan, Andrzej;Zarebski, Adrian;Krawczynska, Karolina;Zurawska, Malgorzata;Zawadzki, Przemyslaw;Milik, Mariusz;Wegrzyn, Paulina;Dobrzanska, Monika;Brzozka, Krzysztof;Kowalczyk, Piotr. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2019.Synthetic Route of C4H7NS The following contents are mentioned in the article:

Maternal embryonic leucine zipper kinase (MELK) is involved in several key cellular processes and displays increased levels of expression in numerous cancer classes (colon, breast, brain, ovary, prostate and lung). Although no selective MELK inhibitors have yet been approved, increasing evidence suggest that inhibition of MELK would constitute a promising approach for cancer therapy. A weak high-throughput screening hit (17, IC₅₀ â‰?5 μM) with lead-like properties was optimized for MELK inhibition. The early identification of a plausible binding mode by mol. modeling offered guidance in the choice of modifications towards compound 52 which displayed a 98 nM IC₅₀. A good selectivity profile was achieved for a representative member of the series (29) in a 486 protein kinase panel. Future elaboration of 52 has the potential to deliver compounds for further development with chemotherapeutic aims. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Synthetic Route of C4H7NS).

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

One-Pot Construction of Sulfur-Rich Thermoplastic Elastomers Enabled by Metal-Free Self-Switchable Catalysis and Air-Assisted Coupling was written by Zhu, Xiao-Feng;Yang, Guan-Wen;Xie, Rui;Wu, Guang-Peng. And the article was included in Angewandte Chemie, International Edition in 2022.Safety of Isopropylisothiocyanate The following contents are mentioned in the article:

Construction of well-defined sulfur-rich macromols. in a facile manner is an interesting but challenging topic. Herein, we disclose how to readily construct well-defined triblock sulfur-rich thermoplastic elastomers via a self-switchable isothiocyanate/episulfide copolymerization and air-assisted oxidative coupling strategy. During self-switchable polymerization, alternating copolymerization of isothiocyanate and episulfide occurs initially due to the lower energy barrier for isothiocyanate insertion with respect to successive episulfide ring-opening. After exhaustion of isothiocyanate, ring-opening polymerization of episulfide begins, providing diblock polymers. Subsequent exposure of the reaction to air leads to a transformation of diblock copolymers into triblock thermoplastic elastomers. This protocol can be extended to diverse isothiocyanates and episulfides, allowing fine-tuning of the performance of the produced sulfur-rich thermoplastic elastomers.

Organocatalysis for the Asymmetric Michael Addition of Aldehydes and α,β-Unsaturated Nitroalkenes was written by Shim, Jae Ho;Cheun, Seok Hyun;Kim, Hyeon Soo;Ha, Deok-Chan. And the article was included in Catalysts in 2022.Formula: C4H7NS The following contents are mentioned in the article:

A mirror image of an aldehyde and α,β-unsaturated nitroalkene were reacted in the presence of (R,R)-1,2-diphenylethylenediamine (DPEN). Thiourea were introduced as an organic catalyst and a selective Michael addition reaction were carried out. The primary amine moiety of DPEN reacts with aldehydes to form enamines, which was activated by the hydrogen bond formation between the nitro groups of α,β-unsaturated nitroalkenes and thiourea. Obtained an asym. Michael product by adding 1,4-enamine to an alkene to form a new carbon-carbon bond. As a result, the primary amine of the chiral diamine were converted to an enamine. The reaction proceeded with a relatively high degree of enantioselectivity, which were achieved using double activation via hydrogen bonding of the nitro group and thiourea. Michael products with a high degree of enantioselectivity (97-99% syn ee) and diastereoselectivity (syn/anti = 9/1) were obtained in yields ranging from 94-99% depending on the aldehydes. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Formula: C4H7NS).
