Buchwald dialkylbiarylphosphines are the most widely used class of ligands in catalysis. The resulting cross-coupling reactions of this class of catalysts have a wide range of applications in both the industry and academia, especially in the fields of medical chemistry, drug discovery, biochemistry, geochemistry, natural product synthesis, small molecule synthesis, and polymer synthesis.
Rutgers Scientists have invented a sterically defined L-shaped NHC ligands analogous to Buchwald dialkylbiarylphosphines. This novel sterically defined L-shaped biaryl NHC ligands on imidazo[1,5-a] pyridine architecture is well defined and stable both in air and moisture complexes with transition-metals and has applications in palladium catalyzed cross-reactions. These ligands can be used to producing commercial salts and complexes at a highly scalable process using Kumada crossing coupling approach, which bypasses the use of chromatography. Many studies have been done to demonstrate the novel features of the ligands including their stable shape and their efficacy in producing salts and complexes that are commercially valued.
