Executive Summary : | N-Heterocyclic carbenes (NHCs) have gained significant research in organometallic chemistry due to their strong sigma donation properties and stability. They are used in various fields, including catalysis, biologically active complexes, redox-active material chemistry, and metallosupramolecular chemistry. NHCs can be enhanced by incorporating NHC donor groups into poly-NHC ligands, which can be used for metal-directed synergistic catalysis. This project aims to synthesize a series of heterobimetallic complexes with shorter metal-metal distances for cooperative catalysis in organic tandem transformations. The project will focus on synthesis of triazolium salts with bulky N-substituents and their use in tandem catalysis. This study aims to synthesize triazolium salts with bulky N-substituents, prepare heterobimetallic complexes PdII/IrIII, PdII/RhIII, and PdII/CuI types, select substrates for tandem catalysis, and apply these complexes in tandem catalysis. The synthetic strategy involves forming bis-TMS compound 2, bis-acetylene compound 3, bis-triazole compound 4, bis-triazolium salt precursor 5, and other heterobimetallic complexes. The project aims to improve the professional and academic profile of the researcher and host institute, as well as improve the catalytic outcomes of the heterobimetallic catalyst. |
