Synthesis of 1,1′-Bis(phosphetano)ferrocenes, a New Class of Chiral Ligands for Asymmetric Catalysis
31 December 1999 (online)
The C2-symmetric, chiral 1,1′-bis(phosphetano)ferrocenes 1 have been prepared from the cyclic sulfates of optically pure, 1,3-diols. They have been tested in the rhodium catalysed hydrogenation of unsaturated substrates.
