Surprising selectivity: The first enantioselective hydroformylations of simple alkenes of type RCH2CH=CH2 to preferentially deliver the branched aldehyde 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. Copyright

Asymmetric hydroformylation catalyzed by an Rh( I) -( R,S) -BINAPHOS complex: Substituent effects in olefins on the regioselectivity

Olefins bearing the larger substituants at the allylic position were hydroformylated in the higher iso/normal selectivity when Rh(I)-(R,S)-BINAPHOS was used as a catalyst. Deuterioformylation of 4,4,4-triphenyl-1 -butene suggests that the higher iso/normal ratio may be attributed to the accelerated CO insertion to the iso-alkylrhodium 7i.
