Controlled insertion into a single P‐P bond of white phosphorus (P4) was achieved by employing a diaryl stabilized stannylene, Ar*2Sn (Ar* = 2,6‐bis(benzhydryl)‐4‐iPr‐phenyl). Conversions of the stannylene with P4 gave a non‐pyrophoric, air‐stable storage compound, which releases P4 quantitively upon irradiation with light (354 or 455 nm). Alternatively, the phosphorus cage is detached by reacting

Recent Advances on Diarylethene‐Based Photoswitching Materials: Applications in Bioimaging, Controlled Singlet Oxygen Generation for Photodynamic Therapy and Catalysis Chem. Asian J. (IF 4.1) Pub Date : 2024-04-05 Sayan Kumar Bag, Adwitiya Pal, Subhendu Jana, Arunabha Thakur
Diarylethenes (DAE), a class of best performing photoswitchable compounds, where the key features of stability, photoisomerization wavelengths, quantum yield and variability in the photoisomers significantly depend on their derivatization. The last decade has witnessed a surge in the engagement of DAEs to different areas of chemical and biological impacts like catalysis in synthetic organic chemistry

Metal‐Free Visible‐Light Catalytic Deoxygenation of Azaaryl N‐Oxides: Harnessing Photons for Efficient Greener Synthesis Chem. Asian J. (IF 4.1) Pub Date : 2024-04-05 Susanta Mandal, Kimron Protim Phukan, Joneswar Basumatary, Biswajit Gopal Roy
Regio‐ and chemo‐selective functionalization of electron deficient azaarenes often required their transformations to corresponding N‐oxides and subsequent removal of oxygen after functionalization to get back the desired substituted azaarenes. An efficient metal‐free visible‐light photo‐redox catalytic deoxygenation of N‐oxides of azaheterocyclic compounds has been developed using acridinium based

One‐Pot Assembly of 2‐Trifluoromethyl Benzothiazole and Benzoselenazole via Copper‐Mediated Three‐Component Cascade Reaction Chem. Asian J. (IF 4.1) Pub Date : 2024-04-05 Yangjie Huang, Chenhui You, Biqiong Hong, Xiaoyan Han, Zhiqiang Weng
A domino one‐pot synthesis of 2‐(trifluoromethyl)benzothiazole via copper‐mediated three‐component cascade reaction starting from the easily accessible starting materials such as o‐iodoanilines, methyl trifluoropyruvate, and elemental sulfur is reported. The present strategy displayed a comprehensive substrate scope and good functional group tolerance and enabled access to a variety of substituted

Luminogenic and Bactericidal Studies of an Acrylonitrile‐based AIEgen Chem. Asian J. (IF 4.1) Pub Date : 2024-04-03 Sagnik De, Debolina Ghosh, Gopal Das
We have synthesized an aggregation induced emissive molecule that exhibits promising photophysical characteristics. The aggregating aptitude is demonstrated by binary solvent mixture and it is emissive in both solution and solid state. The luminogenic characteristics are employed in creating fluorescent inks as well as for the detection of nitro antibiotics in biofluids and in solid support. Moreover
