A Pincer Cobalt Complex as Catalyst with Dual Hydrogenation Activities for Hydrodeoxygenation of Ketones with H2

Reductive deoxygenation of ketones using H_(2) is a highly desirable but also challenging transformation in both chemical synthesis,industrial-scale petroleum and biomass feedstock reforming processes.Herein,we report a cooperative cobalt/Lewis acid (LA)-catalyzed hydrodeoxygenation of ketones using H_(2) as the reductant.In particular,the newly developed pincer cobalt catalyst possesses dual hydrogenation activities for both ketones and alkenes under the same reaction conditions.This reaction features a broad substrate scope,excellent functional-group compatibility,and potential applicability.
