    Description / Table of Contents: Complex Chemistry of Reactive Organic Compounds, V. Reaction of Aliphatic Diazo Compound with Thermolabile Manganese ComplexesAliphatic diazo compounds react with the manganese- tetrahydrofurane complexes 1 and 2, respectively, to yield olefine, ketimine or carbene complexes: 3-diazo-2- butanone (3b) reacts with 2 under intramolecular hydride transfer to give the buten-2- one complex 7, while 3-diazocamphor (3c) leads to the 3-iminocamphor complex 8. Benzolyphenyldiazomethane (3a), diphenyldiazomethane (9a), and its p-substituted derivatives 9b-f are shown to be preliminary stages for the stable carbene complexes 4, 10, and 11, the spectra of which are discussed. The diphenylcarbene ligand can be split off by triphenylphosphine, carbon monoxide, ammonium cerium(IV) nitrate, and by thermolysis.
    Notes: Aliphatische Diazoverbindungen reagieren mit den Mangan-THF- Komplexen 1 bzw. 2 zu Olefin-, Ketimin- oder Carben-Komplexen: Während 3-Diazo-2-butanon (3b) mit 2 unter intramolekularer Hydridverschiebung den Buten-2- on-Komplex 7 ergibt, bildet 3-Diazo-campher (3c) bei Umsetzung mit 2 den 3-Iminocampher-Komplex 8. Benzoylphenyldiazomethan (3a) sowie Diphenyldiazomethan (9a) und seine p- substituierten Derivate 9b-f verhalten sich gegenüber 1 und 2 als Vorstufen für die stabilen Carben-Komplexe 4, 10 und 11, deren Spektren diskutiert werden. Der Diphenylcarben-Ligand in 11a kann mit Triphenylphosphin, Kohlenmonoxid und Ammoniumcer(IV)-nitrat sowie durch Thermolyse abgespalten werden.
