Transfer Hydrogenation in Water [PDF]

The Chemical Record, 2016
AbstractThis article provides an account of our group's efforts in developing aqueous‐phase transfer hydrogenation reactions. It is comprised of mainly two parts. The first part concentrates on asymmetric transfer hydrogenation in water, enabled by Noyori–Ikariya catalysts, while the second part is concerned with the achiral version of the reaction ...
