Reaktion von Acetyl-Uebergangsmetallkomplexen mit Phosphor-Yliden - ein weiteres Beispiel zur Halogenid/Metallat-Analogie

The reaction of the acetyl metal complexes LnM-C(O)CH3Mo> with the phosphorus ylides (CH3)3P=CH2, C2H5(CH3)2P=CH2, (C2H5)3P=CHCH3 and (C4H9)3P=CH2 in the ratio 1:2 yields the corresponding acetyl-substituted ylides R3P=CR'C(O)CH3 3a - d (R = CH3, C2H5, n-C4H9; R' = H, CH3) and phosphonium metalates 4a - d, 6a, b via heterolysis of the Fe-C-?-bond and transylidation.With CH3C(O)Cl an analogous way of reaction is observed, which however can be repeated to give the diacetyl ylides R3P=C(COCH3)2 8a, b (R = CH3, n-C4H9).The new compounds are characterized by spectroscopic methods (NMR, IR) and further reactions.
