A highlyregioselective ruthenium‐catalyzed hydroaminomethylation of olefins is reported. Using easily available trirutheniumdodecacarbonyl an efficient sequence consisting of a water‐gas shift reaction, hydroformylation of olefins, with subsequent imine or enamine formation and final reduction is realized. This novel procedure is highly practical (ligand‐free, one pot) and economic (low catalyst loading

organic polymer catalyst with in situ encapsulated single-site Rh (Rh@CPOL-DPMphos&p-3vPPh3) was developed and employed in heterogeneous hydroaminomethylation of alkenes, affording the corresponding amines in good to excellent regioselectivity and catalytic activity by a one-pot method. The combined actions of hierarchical pore confinement and the biphosphine ligand derived from the POP catalyst contributed

Efficient and Regioselective Ruthenium-catalyzed Hydro-aminomethylation of Olefins
An efficient and regioselective ruthenium-catalyzed hydroaminomethlyation of olefins is reported. Key to success is the use of specific 2-phosphino-substituted imidazole ligands and triruthenium dodecacarbonyl as catalyst. Both industrially important aliphatic as well as various functionalized olefins react with primary and secondary amines to give the corresponding secondary and tertiary amines generally in high yields (up to 96%) and excellent regioselectivities (n/iso up to 99:1).
