Catalysis by Design: Wide-Bite-Angle Diphosphines by Assembly of Ditopic Ligands for Selective Rhodium-Catalyzed Hydroformylation

The assembly makes the bite! Ditopic ligands comprising an anionic NO or NN moiety (shown in blue and gray) and a phosphine moiety (orange) can be assembled with hard metals such as zinc(II) (green) to form bidentate phosphine ligands. This approach led to a rhodium catalysts for the selective hyd...

Description
Summary:The assembly makes the bite! Ditopic ligands comprising an anionic NO or NN moiety (shown in blue and gray) and a phosphine moiety (orange) can be assembled with hard metals such as zinc(II) (green) to form bidentate phosphine ligands. This approach led to a rhodium catalysts for the selective hydroformylation of 1‐octene with linear‐to‐branched ratios up to 21:1 and rates comparable to covalently bound wide‐bite‐angle diphosphine ligands.
