Advances in chemoselective and/or stereoselective semihydrogenation of alkynes

The chemoselective semihydrogenation of alkynes is one of most important reactions in synthetic organic chemistry. During the last decade or so, a multitude of innovative catalytic methods have been developed to address the selective hydrogenation of alkynes. This digest focuses on the recent developments in chemoselective semihydrogenation of alkynes to alkenes. (C) 2017 Elsevier Ltd. All rights reserved.
