Abstract Pd[(S,S)-Et-FerroTANE](Ph)(I) undergoes diastereoselective phosphetane ring-opening with concomitant Pd-to-P phenyl migration on mild heating. Cleavage of the resulting palladacycle with acid yields Pd[FerroCHAIN]I₂, whose reaction with PhMgBr leads to facile opening of the second phosphetane ring and isolation of a complex of a novel C₂-symmetric ligand with P and C stereocenters.
