Abstract

Improved preparations of the disecondary phosphines PhHP(CH2)nPHPh (n = 2, mppe; n = 3, mppp; n = 4, mpppb; n = 6 mpph) by the lithium cleavage of the corresponding ditertiary phosphine Ph2P(CH2)nPPH2 are described and various NMR parameters are reported; a 12 13C isotope effect upon δ(13P) is observed in the case of mppe. Reactions of mppe and mppp with [M(CO)6] (M = Cr, Mo, W) yield 1:1 complexes; both the meso and the rac isomers are produced, are separated and are unequivocally characterized by elemental analysis, vibrational spectroscopy and 1H, 13C and 31P NMR spectroscopy.
