Organic aluminum hydrides catalyze nitrile hydroboration

Economical and eco-friendly aluminum hydrides were shown to be highly efficient catalysts for the solvent-free hydroboration of various nitriles using pinacolborane. The catalytic activities of three organic aluminum hydrides were compared. Mechanism investigation experiments revealed that nitrile w...

More Information
Summary:Economical and eco-friendly aluminum hydrides were shown to be highly efficient catalysts for the solvent-free hydroboration of various nitriles using pinacolborane. The catalytic activities of three organic aluminum hydrides were compared. Mechanism investigation experiments revealed that nitrile was reduced to an imine intermediate by aluminum hydrides. The eco-friendly and highly efficient catalytic hydroboration of nitriles has been elucidated by using organic aluminum hydrides.
