Inventor(s) include Kasula Mamatha; Prabhakar Myadaraveni; Ramu Guda; Rambabu Palabindela; and Srinivas Nerella.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "A Process for the Preparation of Novel Benzothiophene-Substituted Imidazolium Salts as N-Heterocyclic Carbene Precursors. The present invention relates to the synthesis and compositions of novel 1,3-bis(4-(benzo[b]thiophen-2-yl)-2,6-diisopropylphenyl)-1H-imidazol-3-ium salts, specifically the chloride and PF6 salts. These compounds are synthesized through a robust Suzuki cross-coupling method, providing a reliable and efficient route to obtain high-purity imidazolium salts. The resulting salts serve as valuable precursors for the formation of metal-NHC (N-Heterocyclic Carbene) complexes. The disclosed metal-NHC complexes exhibit significant potential in various catalytic processes and the development of advanced materials, owing to their unique electronic properties and steric profiles. This invention not only expands the library of imidazolium salts but also highlights their utility in enhancing reaction selectivity and efficiency in catalysis. The detailed synthesis protocols, characterization, and application methodologies are also disclosed, illustrating the versatility of these compounds in both organic synthesis and material science. The described invention presents a promising avenue for future research and development in catalysis and beyond, offering new insights into the design and application of NHC ligands."
