tricarbonyl phosphine-free iron complexes in reduction of amines. A new cyclopentadienyl iron(II) tricarbonyl complex has been isolated, fully characterized, and applied in hydrogenation. This phosphine-free iron complex is the first Earth-abundant metal complex that is able to catalyze chemoselective reductivealkylation of various functionalized amines with functionalized aldehydes. Such selectivity
The well-defined ruthenium(II) complex A featuring a phosphine sulfonate chelate promotes the introduction of terpene moieties onto cyclic saturated amines through hydrogen “auto” transfers without side alkene reduction. These eco-friendly transformations enable the production of diverse N- and C-terpenoid alkaloids with only water and carbon dioxide as benign side products.
A novel metal-catalyzed strategy to facilitate the synthesis of terpene amines by a homogeneous pathway is reported. Combining the synergy between 3d and 4d transition metals with glycerol, acting as a boosting solvent, leads to an efficient and selective process for the four-component hydroaminomethylation reaction.
