Asymmetric hydrogenation of imines with a recyclable chiral frustrated Lewis pair catalyst. | LitMetric

Asymmetric hydrogenation of imines with a recyclable chiral frustrated Lewis pair catalyst.

Dalton Trans

Institut für Technische und Makromolekulare Chemie, RWTH Aachen University, Worringerweg 1, 52074 Aachen, Germany.

Published: August 2012

A camphor based chiral phosphonium hydrido borate zwitterion was synthesised and successfully applied in the enantioselective hydrogenation of imines with selectivities up to 76% ee. The high stability of the novel chiral FLP-system enables effective recycling of the metal-free catalyst.
