In pharmaceuticals, agrochemical intermediates, OLED/organic semiconductors, and functional polymers, aryl–aryl and heteroaryl–aryl bond formation is ubiquitous.
NHC-trihydroboranes are white solids that are stable to air, water, and even chromatography. However, 1,3-dimethylimidazol-2-ylidene borane is a surprisingly good hydride donor that is comparable to anionic reagents such as NaCNBH3. The reagent can be used for reductive amination procedures and ...
