The phosphorus(III)-bridged [1]ferrocenophanes 1,1'-ferrocenediylphenylphosphine (1), (-)-1,1'-ferrocenediylmenthylphosphine (2) and(-)-bornyl-1,1'-ferrocenediylphosphine (3) have been synthesized via the reaction of 1,1'-dilithioferrocene (TMEDA adduct) and Cl2PR (R = Ph, Men, Bor). Compounds 1 and 2 have been used as ligands in the preparation of the complexes Cp*Mn(Co)(2)[Fe(eta(5)-C5H4)(2)PPh] (4) and (-)-trans-PdCl2[Fe(eta(5)-C5H4)(2)PMen](2) (5). The new compounds 2-5 were characterized by multinuclear NMR, by MS, and 2, 4 and 5 by single-crystal X-ray diffraction. Remarkably, the cyclic dimer anti-exo,exo-1,12-dimenthyl-1,12-diphospha[1.1]ferrocenophane (6) could be isolated and structurally characterized. The thermal ring-opening polymerization of 1, 2 and 3 yielded the poly(ferrocenediylphosphines) 7, 8 and 9. Compounds 2 and 8 were used as chiral ligands in the Rh-catalyzed diastereoselective hydrogenation of folic acid. (C) 2000 Elsevier Science S.A. All rights reserved.
