文摘

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