The mechanism of the intramol. enantioselective rhodium(I)-catalyzed hydroboration of NHC-boranes is investigated by exptl. reactivity measurements and mol. electronic structure calculations, within the framework of the D. Functional Theory and the RPA methods. The crucial role of alkene coordination and the origin of enantioselectivity are discussed. Two possible mechanisms are considered, via either prior hydride migratory insertion or boron migratory insertion. The min. energy computed pathway leads to the enantiomer exptl. observed, therefore supporting the hydride migratory insertion mechanism. Calculations of the final steps of the catalytic cycle, i.e. regeneration of the catalyst and release of the product, give us further insights into the mechanism and rationalize the exptl. results.
After consulting a lot of data, we found that this compound(36620-11-8)Name: Bis(norbornadiene)rhodium (I) tetrafluoroborate can be used in many types of reactions. And in most cases, this compound has more advantages.
