title: A tetraphosphorus ligand for highly regioselective isomerization-hydroformylation of internal olefins.
abstract: A new pyrrole-based tetraphosphorus ligand capable of forming multiple chelating modes has been prepared. Higher regioselectivity has been achieved in the rhodium-catalyzed isomerization-hydroformylations of internal olefins compared with its bisphosphorus analogue.
