Surprising selectivity: The first enantioselective hydroformylations of simple alkenes of type RCH2CHCH2 to preferentially deliver the branchedaldehyde product have been discovered using a new chiral ligand, named bobphos (see scheme). Established ligands are unselective in this reaction or show a slight preference towards the linear aldehyde.
