Transfer hydrogenation of unfunctionalised alkenes using N-heterocyclic carbene ruthenium catalyst precursors

摘要

Transfer hydrogenation of unfunctionalised and aliphatic alkenes in iTrOH/KOH is efficiently catalysed by an olefin-tethered A-heterocyclic carbene ruthenium complex, which also catalyses double bond migration as a competitive and considerably faster process. Homogeneous hydrogenation of olefins is classically performed by direct hydrogenation using molecular H_2.
