Transition Metal Sulfur Ylide Complexes, XXVI. - Reactivity of the (1,3-Diphospha-2-propanone)iron Complex Fe2(CO)6-[(iPr)2N-PC(O)P-N(iPr)2] towards the Ylides Me2S(O)CH2 and Ph3PCH2. Synthesis and Structure of Fe2(CO)6{[(iPr)2N-PCH2]2CO}The metal-functionalized 1,3-diphospha-2-propanone Fe2(CO)6-[(iPr)2N-PC(O)P-N(iPr)2] (3) reacts with two equivalents of Me2S(O)CH2 to give the 1,5-diphospha-3-pentanone derivative 6 by insertion of one CH2 group into each P—C(O) bond. Treatment of 3 with Ph3PCH2 affords the carbonyl-stabilized phosphorus ylide 8. The molecular structure of 6 is established by X-ray analysis. Structure elucidation of 8 is based on spectroscopic data (IR, 1H-, 13C-, 31P-NMR, MS).
Notes:
Das metallierte 1,3-Diphospha-2-propanon Fe2(CO)6[(iPr)2N-PC(O)P-N(iPr)2] (3) reagiert mit zwei Äquivalenten Me2S(O)-CH2 unter Insertion jeweils einer CH2-Gruppe in beide P—C(O)-Bindungen zu dem 1,5-Diphospha-3-pentanon-Derivat 6. Die Behandlung von 3 mit Ph3PCH2 liefert das carbonylstabilisierte Phosphorylid 8. Von 6 wurde eine Röntgenstrukturanalyse durch-geführt. Strukturaufklärung von 8 erfolgte spektroskopisch (IR, 1H-, 13C-, 31P-NMR, MS).
