Palladium-Catalyzed C3-Carbaldehyde Directed Regioselective C2-Thioarylation of Indoles
Chem Asian J. 2024 Apr 5:e202400272. doi: 10.1002/asia.202400272. Online ahead of print.ABSTRACTPalladium-catalyzed thioarylation of indoles by diaryl disulfides in the presence of phenyliododiacetate is reported. The directing potential of weakly coordinating aldehyde group present at 3-position of indole was exploited for regioselective C2-H thioarylation over the possible C4-H functionalization. Mechanistic studies reveal that the process involves initial generation of thioaryl radical followed by sequential C-H activation, thiolate transfer, and reductive elimination.PMID:38577719 | DOI:10.1002/asia.202400272 (Source: ...

Metal-Free Visible-Light Catalytic Deoxygenation of Azaaryl N-Oxides: Harnessing Photons for Efficient Greener Synthesis
Chem Asian J. 2024 Apr 5:e202400147. doi: 10.1002/asia.202400147. Online ahead of print.ABSTRACTRegio- 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 organo-photocatalyst in blue LED light. High efficiency and mildness of this methodology has been demonstrated through higher deoxyge...

Fluoro and Trifluoromethyl Benzoyl Hypoiodite Complexes with Substituted Pyridines
Chem Asian J. 2024 Apr 5:e202400349. doi: 10.1002/asia.202400349. Online ahead of print.ABSTRACTBased on the prior observation of the trifluoroacetate hypoiodite, CF3C(O)OI, demonstrating the largest σ-hole of a neutral halogen bond donor, a series of mono- and bis-carbonyl hypoiodites utilising trifluoromethyl or fluorine substituents at various positions of a parent benzoyl skeleton have been synthesised. The carbonyl hypoiodite complexes were prepared via cation exchange of the silver(I) cations with iodine(I) from the respective silver(I) carboxylates and dicarboxylates as the synthetic precursors. A range of pyridini...

An Air-Stable Storage Compound for White Phosphorus: Reversible Addition to a Stannylene and Chemical Release of P4
Chem Asian J. 2024 Apr 5:e202400168. doi: 10.1002/asia.202400168. Online ahead of print.ABSTRACTControlled 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 the storage compound with PhChChPh (Ch = Se, Te). Despite the recent advances in the directed conversion of P4 using main group eleme...
