Hydroformylation of Internal Olefins to Linear Aldehydes with Novel Rhodium Catalysts

This is the authors' abstract. We don't add key points for this paper.

Unprecedented high activities and selectivities were observed in the hydroformylation of internal octenes to linear products using rhodium catalysts with rigid diphosphane ligands. Dibenzophosphole 1 and a phenoxaphosphane analogue with bite angles of 120 and 119°, respectively, are suited for this.
