Rhodium-catalyzed branched-selective alkyne hydroacylation: a ligand-controlled regioselectivity switch.

Rhodium-catalyzed branched-selective alkyne hydroacylation: a ligand-controlled regioselectivity switch.

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-dppe-rhodium catalyst suggest res...
