Abstract Despite significant research efforts in the past, one of the remaining problems to be solved in industrially important hydroformylation is the chemoselective low‐pressure hydroformylation of internal alkenes. We report here on a new class of phosphabarrelene/rhodium catalysts 2 that display very high activity towards hydroformylation of internal alkenes with an unusually low tendency towards alkene isomerization. Preparation of new phosphabarrelene ligands, studies of their coordination properties, as well as results obtained in the rhodium‐catalyzed hydroformylation of cyclic and acyclic internal alkenes are reported.
