Abstract
Abstract Homogeneous hydrogenations and hydrofunctionalizations of carbon–oxygen and carbon–carbon bonds with copper catalysts are reviewed herein. The title literature revision covers mostly contributions made over the last decade on hydrogenation of carbonyl compounds, alkenes, alkynes, and CO 2 , as well as hydrosilylation, hydroboration, hydroamination, hydroallylation, hydroalkylation, hydrocarboxylation, or hydrocarbonylation of either alkenes, alkynes, allenes, carbonyl compounds, or CO 2 . This contribution features well‐defined copper catalytic precursors as well as mixtures of various copper sources, either Cu(I) or Cu(II) salts, and ligands for in situ formation of the catalytic systems. Asymmetric copper catalysis is also highlighted in several kinds of transformations throughout this review.
