Extensive Studies on the Synthesis and Characterization of π‐Arene Chromium Complexes and Their Performance in SNAr and Suzuki–Miyaura Cross‐Coupling Reactions

open access: yesChemistry – An Asian Journal, EarlyView.
π‐Arene chromium complexation: An advancement in the direct thermolysis approach has been demonstrated, showcasing its broad applicability with over 50 examples, including heterocyclic ring‐tethered and densely functionalized poly(hetero)aryl Cr(CO)₃ complexes, achieving very high yields. Abstract We report an efficient synthesis of a series of new (η6‐

Advances in Metal‐Free Transamidation: A Sustainable Approach to Amide Bond Formation

open access: yesChemistry – An Asian Journal, EarlyView.
This review highlights the recent developments of transamidation reactions under metal‐free reaction conditions. Various amines including weak nucleophilic amines such as aromatic amines have been used to achieve the transamidation reactions under mild and relatively green reaction conditions. Abstract The amide functionalities are a crucial functional

Reusable Selenenyl Iodide‐Initiated Cascade Cyclization of Polyenes with N‐terminating Groups

open access: yesChemistry – An Asian Journal, EarlyView.
A cascade cyclization of polyenes with N‑terminating groups, initiated by an isolable selenenyl iodide, was developed. The cavity‑shaped substituent stabilized both the selenenyl iodide and the selenenic acid generated via β‑selenoxide elimination, enabling the regeneration of selenenyl iodide.

Increasing Redox Potential of Pyromellitic Diimide by Chemical Modifications: Toward High‐Voltage Organic Positive Electrode for Lithium Battery

open access: yesBatteries &Supercaps, EarlyView.
Chemical modifications of soluble pyromellitic diimide derivatives with bromo‐ and cyano‐ electron‐withdrawing groups instead of hydrogen lead to an increase of redox potential of 210 and 420 mV respectively compared to the reference. Lithium batteries are considered as the most promising electricity storage solution to support the energy transition ...
