Electro-oxidative methylation of 2-isocyanobiaryls using N,N-dimethylformamide (DMF) as carbon source: Synthesis of 6-methylphenanthridines
Chem Asian J. 2024 Mar 15:e202400176. doi: 10.1002/asia.202400176. Online ahead of print.ABSTRACTA benign electrochemical method to access 6-methylphenanthridines from 2-isocyanobiaryls using N,N-dimethylformamide (DMF) as a methyl source is reported. The protocol operates at ambient temperature without the need for harmful methylating reagents. Mechanistic studies suggested that DMF delivered a methylene synthon, followed by reduction at the cathode and tautomerization. The method offers environmental benefits by avoiding metal-based reagents and harsh conditions.PMID:38489229 | DOI:10.1002/asia.202400176 (Source: Chemist...

Facile Preparation of Impalement Resistant, Mechanically Robust and Weather Resistant Photothermal Superhydrophobic Coatings for Anti-/De-icing
Chem Asian J. 2024 Mar 13:e202400110. doi: 10.1002/asia.202400110. Online ahead of print.ABSTRACTPhotothermal superhydrophobic coatings hold great promise in addressing the limitations of conventional superhydrophobic anti-icing coatings. However, developing such coatings with excellent impalement resistance, mechanical robustness and weather resistance remains a significant challenge. Here, we report facile preparation of robust photothermal superhydrophobic coatings with all the above advantages. The coatings were prepared by spraying a dispersion consisting of fluorinated silica nanoparticles, a silicone-modified polyes...

Synthesis of Naphthalimide Azocarboxylates Showing Turn-on Fluorescence by Substitution Reaction With Sulfinates
Chem Asian J. 2024 Mar 14:e202400145. doi: 10.1002/asia.202400145. Online ahead of print.ABSTRACTThe synthesis and characterization of sulfinate addition-responsive fluorescent molecules are described. We found that addition reaction of sulfinates to naphthalimide-substituted azocarboxylates afforded the corresponding sulfonyl hydrazides with high fluorescence quantum yields (up to 0.91 in THF and 0.54 in methanol), which exhibited a large Stokes shift (105 nm) in protic methanol solvent, while the unsubstituted hydrazide and the sulfonyl-position isomer showed no fluorescence in polar solvents.PMID:38483258 | DOI:10.1002/...

Carbazole Based Smaragdyrins: Synthesis, Aromaticity Switching, and Formation of a Spiro-Dimer
Chem Asian J. 2024 Mar 8:e202400029. doi: 10.1002/asia.202400029. Online ahead of print.ABSTRACTCarbazole-incorporated smaragdyrin BF2-complex 3 was synthesized by SNAr reaction of 3,5-dibromo-8-mesityl-BODIPY 1 with 3,6-di(tert-butyl)-1,8-di(pyrrol-2-yl)carbazole 2 as a nucleophile. Demetalation of 3 with ZrCl4 gave the corresponding smaragdyrin free base 4 in a good yield. Oxidations of 3 and 4 with MnO2 gave smaragdyrins 5 and 6, respectively, both followed by aromaticity switching, since the oxidized products showed a moderate paratropic ring current owing to their 20π-electronic circuits. Further, treatment of 4 with...
