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.
Notes:
Die Kondensation des μ-Carbinkomplexes {(η5-C5H5)2(CO)2Fe2(μ-CO)(μ-CSMe)}+SO3CF3- (6) mit den Phosphanen 2,4,6-R3C6H2PH(SiMe3) (7) (a: R = Me, b: R = iPr, c: R = tBu) liefert die Komplexe (η5-C5H5)2(CO)2Fe2(μ-CO)(η-C=PC6H2R3-2,4,6) 9a-c, die die neuartigen Isophosphaalkine C≡P-Aryl als Brückenliganden tragen. Von 9 a wurde eine Röntgenstrukturanalyse durchgeführt.
