 Title    Darstellung und Charakterisierung von "Nitrenkomplexen"  
 Abstract    des Molybdän und Wolfram der Zusammensetzung [(^-C5H5)OM]2(/*-NCOOC2H5)2 (M = Mo, W) und [(^-C5H5)0Mo]2(^-NC02C2H5)(^-0) Synthesis and Characterization of "Nitrene Complexes" of Molybdenum and Tungsten of Composition [(^-C5H5)0M]2(/<-NC02C2H5)2 (M = MO, W) and [(^-C5H5)0Mo]2(^-NC00C2H5)Gu-0) The photolytical reactions of 7? 5 -C5H5Mo(CO)3CH3 (1) or 7? 5 -C5H5W(CO)3CH3 (2) with N3C02C2H5 (3) in CH2C12 yield the "nitrene" complexes [(^-CsHsJMoOJ^-NCC^Hsfe (4), [(r? 5 -C5H5)W0]2(/u-NC02C2H5)2 (5) and [(^-CsHsJMoOM^-NCO^HsM^-O) (6) together with some *? 5 -C5H5Mo(CO)3Cl (7) and ^ 5 -C5H5W(CO)3Cl (8), proving that the solvent takes part in the reaction. Compounds 4, 5 and 6 contain bridging imido groups, arising from the capture of probably free nitrenes NC02C2Hs by organometallic species. Evidence for the presence of free nitrenes in the reaction medium is provided by the isolation of urethane (9), tetrachlorethene (10), 7 and 8 as secondary products.
