Cao, Xinhua published the artcileFluorescence and Morphology Modulation in a Photochromic Diarylethene Self-Assembly System, COA of Formula: C15H14Cl2S2, the publication is Langmuir (2011), 27(8), 5090-5097, database is CAplus and MEDLINE.

Switchable supramol. self-assemblies on the basis of interaction between melamine group containing photochromic diarylethene unit (DTE) and naphthalimide derivate (1) were designed and fabricated. 1 can gelate several aprotic solvents with different morphologies. The gel turned into partial gel in Et acetate with the addition of DTE as a guest mol. Both the absorption and fluorescence spectra of the assembly can be reversibly switched by alternating UV/visible light irradiation Meanwhile, the morphol. of the coassembly of 1₂·DTE changed to film from original pieces of gel 1 in Et acetate. When 1₂·DTE was irradiated by UV light, the film morphol. was converted into aggregated flakes. Moreover, the surface wettability of the complex can also be switched by light irradiation The photochromic diarylethene unit is able to modulate the fluorescence and morphol. of the assembled system only by virtue of light irradiation Therefore, these results provide further insights into fluorescence and morphol. controlling, especially application in upscale smart responsive materials.

Liu, Renxiang published the artcileModified and Scalable Synthesis of N-Tosyl-4-Chlorobenzenesulfonimidoyl Fluoride (SulfoxFluor): Direct Imidation of Sulfinyl Chlorides with Chloramine-T Trihydrate, Category: chlorides-buliding-blocks, the publication is Organic Process Research & Development (2022), 26(2), 380-386, database is CAplus.

A general and practical method for the preparation of N-Tosyl-4-chlorobenzenesulfonimidoyl fluoride (SulfoxFluor) and its adaptation to a large scale was disclosed. Starting from readily available 4-chlorobenzenesulfonyl chloride, chloramine-T trihydrate and potassium fluoride, SulfoxFluor was prepared on a hectogram scale in 63% overall yield with simple purification techniques. The use of chloramine-T trihydrate (instead of anhydrous chloramine-T) was a significant improvement over previous work, which streamlined the process and avoided the risk of explosion during drying or heating. This research not only established a reliable method for the scale-up synthesis of SulfoxFluor but also provided an insight into the imidation of sulfinyl chlorides with chloramine-T in the presence of water.

A novel palladium-catalyzed aminomethylamination of aminoalkenes with an aminal, functioning not only as an aminomethylation reagent but also as an oxidant, was developed. This direct and operationally simple protocol provides a fundamentally novel and unique approach toward the synthesis of 2-(2-aminoethyl)indoles, e.g., I, and 2-(2-aminoethyl)pyrrolidines, e.g., II (X-rays single crystal structures for both compounds shown), which are important building blocks in synthetic organic chem. The unity of this method was highlighted by the rapid synthesis of Alosetron, a drug used for the treatment of irritable bowel syndrome.

A straightforward strategy involving photocatalysis has been established for accessing trisulfide dioxides R¹SSSO₂R² (R¹ = Et, t-Bu, 1-adamantyl, 2-MeC₆H₄, etc.; R² = cyclopropyl, Ph, 4-FC₆H₄, 2-thienyl, etc.) from readily achieved sym. tetrasulfides R¹S₄R¹ and sulfinic acids R²SO₂H. Stern-Volmer anal. and radical quenching experiments demonstrated the occurrence of a single electron transfer between the photocatalyst and sulfinic acid. Bioactive mols. such as the antihypertensive drug captopril, allicin derivatives, amino acids and terpenes were efficiently and reversibly linked through sulfur-sulfur covalent bonds. Furthermore, flow-setup syntheses of trisulfide dioxides were successfully achieved on the gram scale, indicating the great potential of the developed protocol for practical industrial applications.

An unprecedented 1,3-dipole cycloaddition between acyclic CF₃-ketimines and N-benzyl azomethine ylide has been allowed by tungsten catalysis, furnishing a range of novel imidazolidines bearing a trifluoromethylated tetrasubstituted carbon center. This reaction appears as one of rare examples that challenging acyclic CF₃-ketimines have been engaged in 1,3-cycloaddition reactions. The capability for gram-scale synthesis and variant derivatizations of cycloaddition adducts illustrates the synthetic potential of this approach. This protocol provides a facile access to a rapidly enlarging pool of motifs with a trifluoromethylated fully substituted carbon.
