Article abstract of DOI:10.1002/anie.201100956

It's all in the ligand: By choice of the appropriate diphosphine ligand a previously linear-selective alkyne hydroacylation process can be "switched" to be highly branched-selective (see scheme, l=linear, b=branched). Structural data for the ortho-iPr-dpp
