    Notes: Transition-Metal-Substituted Diphosphenes, XXVII[1]. - Synthesis and Structure of the Diphosphirane (η5-C5Me5)(CO)2Fe-PH[Cr(CO)5(η5-C5Me5)(CO)2FePH2 (5), prepared from (η5-C5Me5)(CO)2Fe-P(SiMe3)2 and ethanol, reacts with one equivalent of ClP = C(SiMe3)2 to give the diphosphirane (η5-C5Me5)(CO)2FePH (8). Compound 8 is converted into the iron chromium complex [(η5-C5Me5)(CO)2Fe-H]Cr(CO)5(9). In contrast, the reaction of 5 with two equivalents of ClP=C(SiMe3)2 results in the formation of the cyclotri-phosphane [(η5-C5Me5)(CO)2Fe-[CH(SiMe3)2] (12). The molecular structure of 9 is elucidated by single-crystal X-ray analysis.

    Notes: Rearrangements of the Metallodiphosphapropenes (η5-C5Me5)(CO)2FeP(SiMe3  -  P = C(R)(SiMe3) (R = SiMe3, Ph)Heating of a methylcyclohexane solution of (η5-C5Me5)-(CO)2FeP(SiMe3)  -  P = C(SiMe3)2 (1a) gives rise to the insertion of the P = C moiety into the CH bond of a ring methyl group with formation of the chelate complex η5-ηC5Me4CH2P-[CH(SiMe3)2]P(SiMe3)Fe(CO)2 (2) which is converted into the pentacarbonylchromium derivative [5-C5Me4CH2P[CH-(SiMe3)2]P(SiMe3)[Cr(CO)5]Fe(CO)2] (3). In contrast, a similar treatment of (5-C5Me5)(CO)2FeP(SiMe3)  -  P = C(Ph)(SiMe3) (1 b) furnishes the diphosphirane (5-C5Me5)(CO)2FeP  -  C(Ph)-SiMe3)  -  P (SiMe3) (5). By chromatography of its (CO)5Cr adduct 6, the P  -  Si bond is hydrolyzed to give the (diphosphirane)-chromium complex [(5-C5Me5)(CO)2FeP-C(Ph)(SiMe3)P(H)]-Cr(CO)5 (8). The molecular structures of 3 and 8 are determined by single-crystal X-ray analysis.
