3.3 Gas-Phase Selective Asymmetric Hydrogenation
Chiral hydrogenation catalysts that have been developed in the last decades for asymmetric transformations can also be applied in the form of SILP systems. The continuous gas-phase hydrogenation of methylacetoacetate (MAA) with Ru-SILP catalysts
was reported in 2011 [25] (Scheme 3.2).
