The metal-functionalized 1,3-diphospha-2-propanone Fe2(CO)6 (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). - Key Words: 1,3-Diphospha-2-propanone, iron complex of / Methylene insertion / Ylides
