Bidentate Ligands by Self-Assembly through Hydrogen Bonding:A General Room Temperature/Ambient Pressure Regioselective Hydroformylation of Terminal Alkenes

摘要

The 6-DPPon(1)/rhodium catalyst allows for the first time a room temperature/ambient pressure regioselective hydroformylation of terminal al-kenes with low catalyst loadings in good activity.The generality of this catalyst under these conditions was demonstrated for a wide range of structurally diverse alkenes equipped with many important functional groups.Thus,this practical and highly selective hydroformylation protocol,which omits the need for special pressure equipment,should find wide application in organic synthesis.
