    Description / Table of Contents: Diazoalkane Complexes of Nickel(0) and Palladium(0) and Their Relevance to Carbenoid ReactionsA series of diazoalkane complexes with the composition ML2(diazoalkane) [M = Ni, Pd; L = tBuNC, PPh3; diazoalkane = 9-diazofluorene or diphenyldiazomethane] have been prepared and characterized, and their thermolysis and displacement reactions investigated. The nickel complexes catalyse a carbenoid reaction which leads to ketenimine formation. A carbene complex having the formula Pd(PPh3)2(C13H8) was obtained by low temperature thermolysis of Pd(PPh3)2(9-diazofluorene).

Die Nickelkomplexe katalysieren eine Carbenoidreaktion, die zur Keteniminbildung führt. Tieftemperaturthermolyse von Pd(PPh3)2(9-Diazofluoren) lieferte einen Carbenkomplex der Zusammensetzung Pd(PPh3)2(C13H8).

    Notes: A novel class of urea-formaldehyde condensation resins containing covalently bound metallophthalocyanine [M = A1(III), Co(II), Ni(II), or Cu(II)] was synthesized from [tetrakis(methyl-olamide)phthalocyaninato] metal complexes and dimethylolurea in aqueous solution by heating at 120°C for 10 h, followed by heating at 150°C for about 1 day. The structures of the polymers obtained were characterized by infrared and reflection electronic spectra. The thermal stabilities of the resins were evaluated by dynamic thermogravimetric analyses. The resin containing 21.3 wt % Ni(II)-metallophthalocyanine had the greatest thermal stability, with 82 wt-% char yield at 600°C in air atmosphere.
