Synthesis of bis-1,3-(benz)azoles catalyzed by palladium-PEPPSI complex-based catalysts and the study of photophysical properties. CHEMOSPHERE 2022; 301:134751. [PMID: 35490757 DOI: 10.1016/j.chemosphere.2022.134751] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Revised: 04/10/2022] [Accepted: 04/24/2022] [Indexed: 06/14/2023]
Abstract
Many biologically potent molecules have been identified to consist of benzo [b]azoles skeleton that are regarded to be the most important drug targets. Specifically, bis-benzo azoles have been the privileged conjugated structures due to their broad applications in environmental catalysis, and synthesis of various polymers, advanced materials, ligands, and natural products. Considering the significant features, different approaches have been attempted to synthesize such molecules via C-H activations by utilizing the transition metal complexes. In this study, we have developed facile and efficient Pd-based N-heterocyclic carbene (NHC) complexes, i.e., Pd-PEPPSI (Palladium-Pyridine Enhanced Pre-catalyst Preparation Stabilization and Initiation) catalysts that could successfully activate C-H bond and construct C-C bond between two 1,3-(benz)azoles via intermolecular oxidative homo-coupling reaction. The prepared Pd NHC catalysts were characterized by NMR and XPS. Pd NHCs concern about the special electronic and steric factors as the strong σ-donating and poor π-accepting properties of these nuclei renders great diversity in the field of transition metal catalysis as ancillary ligands and catalysts. Key factors of this methodology include low catalyst load, good substrate scope (even with sterically hindered substituted components), but no necessity of any extraneous ligands/oxidants and working at ambient reaction conditions with good to excellent yields of the products. Further, the targeted bis azole molecules have been characterized by single-crystal X-ray diffraction (XRD), nuclear magnetic resonance (NMR), and cyclic voltammetric (CV) studies. The fluorescence and absorption spectra of a few of the synthesized compounds revealed that the electron-donating groups present on N-substituent dictate the absorption and emission bands.

Abstract
Transition metal-mediated C-H bond activation and functionalization represent one of the most straightforward and powerful tools in modern organic synthetic chemistry. Bi(hetero)aryls are privileged π-conjugated structural cores in biologically active molecules, organic functional materials, ligands, and organic synthetic intermediates. The oxidative C-H/C-H coupling reactions between two (hetero)arenes through 2-fold C-H activation offer a valuable opportunity for rapid assembly of diverse bi(hetero)aryls and further exploitation of their applications in pharmaceutical and material sciences. This review provides a comprehensive overview of the fundamentals and applications of transition metal-mediated/catalyzed oxidative C-H/C-H coupling reactions between two (hetero)arenes. The substrate scope, limitation, reaction mechanism, regioselectivity, and chemoselectivity, as well as related control strategies of these reactions are discussed. Additionally, the applications of these established methods in the synthesis of natural products and exploitation of new organic functional materials are exemplified. In the last section, a short introduction on oxidant- or Lewis acid-mediated oxidative Ar-H/Ar-H coupling reactions is presented, considering that it is a very powerful method for the construction of biaryl units and polycylic arenes.
