Branched-regioselectivehydroformylation of allylic o-DPPB esters has been accomplished with mono- and disubstituted alkene functions in good to excellent yields and selectivities. Optimized reaction conditions allowed the reaction of even trisubstitued alkenic functions. These reactions occur as a result of a significant rate-accelerating effect exerted by the catalyst-directing o-DPPB group, as exemplified
