    Description / Table of Contents: Organometallic Lewis Bases, XXXII. Preparation of Dinuclear Complexes via Organometal ArsinesThe organometal arsines M — As(CH3)2 [M=C5H5(CO)3Mo, C5H5(CO)3W, C5H5(CO)2Fe] react with metal carbonyls M′— CO [M′=Cr(CO)5, Mo(CO)5, W(CO)5, Mn(CO)2C5H5, Fe(CO)4, Fe(CO)(NO)2, Co(CO)2NO and Ni(CO)3] in the usual manner to form the dinuclear complexes M — As(CH3)2 — M′ (2-4). Upon reaction with Co(CO)2C5H5 further CO elimination occurs with direct formation of arsenic-bridged complexes with metal-metal bonds (5a, b). Attempts to convert the dinuclear complexes M — As(CH3)2 — M′ photochemically into complexes with metal-metal bonds were successful only in the cases already known.
    Notes: Die Organometall-Arsine M—As(CH3)2 [M=C5H5(CO)3Mo, C5H5(CO)3W und C5H5(CO)2Fe] reagieren mit Metallcarbonylen M′— CO [M′= Cr(CO)5, Mo(CO)5, W(CO)5, Mn(CO)2C5H5, Fe(CO)4, Fe(CO)(NO)2, Co(CO)2NO und Ni(CO)3] nach üblichen Verfahren unter Bildung der Zweikernkomplexe M — As(CH3)2 — M′ (2-4). Bei Umsetzung mit Co(CO)2C5H5 bilden sich unter weiterer CO-Abspaltung direkt arsenverbrückte Komplexe mit Metall-Metall-Bindungen (5a, b). Versuche zur photochemischen Umwandlung der Zweikernkomplexe M — As(CH3)2 — M′ in Komplexe mit Metall-Metall-Bindung waren nur für die bereits bekannten Fälle erfolgreich.
