Abstract: | Transition Metal Substituted Acylphosphanes and Phosphaalkenes. 17. Synthesis and Structure of the μ-Isophosphaalkyne Complexes [(η5-C5H5)2(CO)2Fe2(μ-CO)(μ-C?PC6H2R3)] (R = Me, iPr, tBu) . Condensation of (η5-C5H5)2(CO)2Fe2(μ-CO)(μ-CSMe)}+SO3CF3? ( 6 ) with 2,4,6-R3C6H2PH(SiMe3) ( 7 ) ( a : R = Me, b : R = iPr, c : R = tBu) affords the complexes (η5-C5H5)2(CO)2Fe2(μ-CO)(η-C?PC6H2R3-2,4,6) ( 9 a–c ) with edge-bridging isophosphaalkyne ligands as confirmed by the x-ray structure analysis of 9 a . |
