Ruthenium hydride-catalyzed addition of aldehydes to dienes leading to β,γ-unsaturated ketones

Article abstract of DOI:10.1021/ja806929y

An efficient cross-addition reaction of dienes with aldehydes was developped by using RuHCl(CO)(PPh₃)₃ as a catalyst to give a wide variety of β,γ-unsaturated ketones, where a π-allylruthenium species, derived from hydroruthenation of diene, may be involved as a key intermediate. Copyright
