Borylation occurs selectively at the least sterically hindered and least electron rich primary C–H bond in a range of acetals, ethers, amines, and alkyl fluorides. [10] Additionally, no reaction is shown to occur in the absence of primary C–H bonds, for example when cyclohexane is the substrate. See more Metal-catalyzed C–H borylation reactions are transition metal catalyzed organic reactions that produce an organoboron compound through functionalization of aliphatic and aromatic C–H bonds and are therefore useful … See more • Organoboron chemistry • Reactions of organoborates and boranes • Corey–Itsuno reduction See more Aliphatic C–H borylation As first described by Hartwig, alkanes can be selectively borylated with high selectivity for the primary C–H bond using Cp*Rh(η -C6Me6) … See more WebPara C−H borylations (CHB) of tetraalkylammonium sulfates and sulfamates have been achieved using bipyridine-ligated Ir boryl catalysts.
