    Description / Table of Contents: On the Reactivity of (η5-C5Me5)(CO)2FeP(SiMe3)2 Toward P-Chloromethylene phosphanesThe reaction of (η5-C5Me5)(CO)2FeP(SiMe3)2 (2) with three equivalents of Cl—P=C(SiMe3)2 (3a) afforded the 3-methanediyl-1,3,5,6-tetraphosphabicyclo[3.1.0]hex-2-ene (η5-C5Me5)(CO)2Fe— (6a). In contrast, 2 reacts with two equivalents of Cl—P=C(Ph)SiMe3 (3b) to give the thermolabile (η5-C5Me5) · (CO)2Fe—P[P=C(Ph)SiMe3]2 (4b) which decomposed during the reaction with further 3b. 4 b was also obtained from (η5-C5Me5)(CO)2Fe—P(SiMe3)—P=C(SiMe3)2 (1a) and two equivalents of 3b.
    Notes: Die Reaktion von (η5-C5Me5)(CO)2FeP(SiMe3)2 (2) mit drei Äquivalenten des P-Chlorphosphaalkens Cl—P = C(SiMe3)2 (3a) lieferte das 3-Methandiyl-1,3,5,6-tetra-phosphabicyclo[3.1.0]hex-2-en (η5-C5Me5)(CO)2Fe— (6a). Demgegenüber reagiert 2 mit zwei Äquivalenten an Cl—P=C(Ph)SiMe3 (3b) zu der thermolabilen Verbindung (η5-C5Me5)(CO)2Fe—P[P=C(Ph)SiMe3]2 (4b), die sich bei der Behandlung mit überschüssigen 3b zersetzt. 4b wird auch bei der Umsetzung von (η5-C5Me5)(CO)2FeP(SiMe3)—P=C(SiMe3)2 (1a) mit zwei Äquivalenten 3b erhalten.
