  Reaction of [Cp(CO)(2)M=P=C(SiMe3)(2.)] (where M = Mo (3a), W (3b)] with 2 equiv of the arsaalkene PhC(O)As=C(NMe2)(2) afforded the metalloarsaalkenes Cp(CO)(2)M-As=C(Ph)-O-P-O-C(Ph)=As-C(SiMe3)(2) [where M= Mo (6a), W (6b)]. Small amounts of [eta(3):eta(3)-(Me3Si)(2)CPAs-AsPC(SiMe3)(2)}- Mo(CO)(2)Cp}(2)] (7) were formed as a minor product. Similarly, 3b and 2 equiv of 4-EtC6H4C(O)As= C(NMe2)(2) gave rise to the formation of [Cp(CO)(2)W-As=C(4-EtC6H4)-O-P-O-C(4-EtC6H4)=As- C(SiMe3)(2)] (8). However, treatment of 3a and 3b with an excess of tBuC(O)As=C(NMe2)(2) yielded cocrystals of the eta(3)-2-phospha-1,3-diarsaallyl complexes [Cp(CO)(2)Meta(3)-tBuC(O)AsPAsC(O)tBu}] [where M = Mo (13a), W (13b)] and the eta(3)-1,2,3-triarsaallyl complexes [Cp(CO)(2)Meta(3-)tBuC(O)AsAsAsC-(O)tBu}] [where M = Mo (14a), W (14b)] in varying ratios. Reaction of 3a with Me3SiAs=C(NMe2)(2) afforded the dinuclear 1,2-diphosphapropene complex [eta(2):eta(2)-(Me3Si)(2)C=P-P(H)-C(H)(SiMe3)(2)}Mo-(CO)(2)Cp}(2)] (15). The novel compounds 6a,b, 8, 13a,b, 14a,b, and 15 were characterized by means of spectroscopy (IR and H-1, C-13H-1}, P-31 NMR). Moreover the molecular structures of 7, 8, 13a, 14a, 13b, 14b, and 15 were determined by X-ray diffraction analyses.
• Metallophosphaalkenes—from Exotics to Versatile Building Blocks in Preparative Chemistry

  AbstractThe chemistry of low‐valent organophosphorus compounds such as phosphaalkenes and phosphaalkynes has undergone rapid development in the last two decades. This development also includes the coordination chemistry of these species, which can act as versatile ligands in metal complexes. Metallophosphaalkenes are compounds in which one or more of the organic substituents on the PC unit is replaced by a transition metal complex fragment. Metallophosphaalkenes have emerged from an existence as laboratory curiosities to become a link between main group and organometallic complex chemistry. The great richness of their chemistry not only mirrors the specific properties of the individual building block, but also shows novel and individual traits. Particular examples are cycloadditions of these electron‐rich heteroalkenes with electron‐deficient alkenes, alkynes, azo, and diazo compounds. These often lead to novel types of reaction and compounds. Metallophosphaalkenes are also important as intermediates in all metal‐assisted cyclooligomerizations of phosphaalkynes.

  AbstractDie Reaktion des Metallo‐1,2‐diphosphapropens (η5‐tBuC5H4)(CO)2FeP(SiMe3)PC(SiMe3)2 mit (Cycloocten)Cr(CO)5 liefert das Pentacarbonylchrom‐Addukt eines 1,2‐Diphosphaferrocenes [(η5‐tBuC5H4)η5‐1‐[Cr(CO)5]‐3,4‐(Me3SiO)2‐5‐(Me3Si)P2C3}Fe] (1c). Das Carbonyl‐metall‐freie 1,2‐Diphosphaferrocen [(η5‐tBuC5H4)η5‐3,4‐(Me3SiO)2‐5‐(Me3Si)P2C3}Fe] (2 c) entsteht bei der Umsetzung von (η5‐tBuC5H4)(CO)2FeBr mit (Me3Si)2PP = C(SiMe3)2 in Toluol bei 60°C. Das 1,2‐Diphosphaferrocen [(η5‐1,3‐tBu2C5H3)η5‐3,4‐(Me3SiO)2‐5‐(Me3Si)P2C3}Fe] (2 b) reagiert mit den Hexacarbonylen von Molybdän und Wolfram bei Bestrahlung zu den Pentacarbonylmetall‐Addukten 8 (M = Mo) und 9 (M = W). Ein entsprechender Mangankomplex 10 wird bei der photochemischen Reaktion von 2 b mit (MeC5H4)Mn(CO)3 gebildet. Im Gegensatz hierzu entsteht bei der Behandlung von 2 b mit Co2(CO)8 der dreikernige Komplex [(η5‐1,3‐tBu2C5H3)η5‐1,2‐[Co2(CO)6]‐3,4‐(Me3SiO)2‐5‐(Me3Si)P2C3} Fe] (11). Konstitution und Konfiguration der Verbindungen 1 c, 2 c, und 8 – 11 wurden durch Elementaranalysen und Spektren (IR, 1H‐, 13C‐, 31P‐NMR, MS) ermittelt. Von 11 wurde zusätzlich eine Einkristall‐Röntgenstrukturanalyse durchgeführt.
