摘要：

Different routes to tripod ligands CH(3)C(CH(2)C(5)H5)(CH(2)PR(2)')(CH(2)PR(2) "), 5, containing a cyclopentadienyl unit and two additional donor groups are described. The syntheses involve CH(2)OCH(2)C(CH(3))(CH(2)C(5)H(5)), 2, or CH(3)C(CH(2)Cl)(CH(2)Br)(CH(2)C(5)H(5))(5) 12, respectively as intermediates. The compounds 2 and 12 respectively are obtained from CH(2)OCH(2)(CH(3))(CH(2)OSO(2)CH(3)), 1, or CH(3)C(CH(2)Cl)(CH(2)Br)(CH(2)OSO(2)CF(3)), 11, by reaction with CpMgCl. The capability of the ligand 5 to coordinate to a transition metal via all its three donor groups is documented by the analytical, spectroscopical and X-ray structural characterisation of CH(3)C(CH(2)-eta(5)-C(5)H(4))(CH(2)PPh(2))(2)Mn(CO), 13.
