Abstract
Ruthenium hydride complexes, which can be easily prepared from ruthenium trichloride in high yields, are readily available for the migration reaction of carbon- carbon unsaturated bonds under neutral conditions. The functional groups, being capable of (n-π) or (π-π) conjugation with the migrated carbon-carbon unsaturation, control regioselectively the double bond migration. Utility of the double bond migration reactions catalyzed by ruthenium hydride complexes is demonstrated by several examples.
