Cyclopentadienyl dicarbonyl

Dialkyl- und 2,3-Diaryl-oxirane bilden mit Natrium-cyclopentadienyl-dicarbonyl-eisen ein Alkanolat, das thermisch unter Inversion in ein trans- Aiken (>96°/od-Th ) zer-fallt3. Beim Behandeln des Alkanolats mit Tetrafluoroborsaure bzw. Hexafluorophos-phorsaure erhalt man einen Aiken-Komplex, der bei kurzzeitigem Erhitzen mit Jodid unter Erhalt der Konfiguration das c/.s-Aiken liefert4 ... [Pg.528]

Another Ti-catalyzed domino reaction has been developed by Riick-Braun and coworkers [313] using 3-cyclopentadienyl (dicarbonyl)iron-substituted enals 6/4-129 and primary amines 6/4-130 to give dihydropyrrolones 6/4-131 (Scheme 6/4.32). [Pg.478]

Bis(ij-cyclopentadienyl)dicarbonyl has also been prepared electrochemi-cally. When DME solutions of Cp2TiCl2 were electrolytically reduced in an atmosphere of CO, high yields of Cp2Ti(CO)2 (1) were obtained (24). [Pg.322]

An interesting method is to protect one double bond by addition of cyclopentadienyl dicarbonyl iron during hydrogenation and afterwards to regenerate the product (equation 17)57. [Pg.1000]

Alike metallocomplex anion-radicals, cation-radicals of odd-electron structure exhibit enforced reactivity. Thus, the 17-electron cyclopentadienyl dicarbonyl cobalt cation-radical [CoCp(CO)2] undergoes an unusual organometallic chemical reaction with the neutral parent complex. The reaction leads to [Co2Cp2(CO)4]. This dimeric cation-radical contains a metal-metal bond unsupported by bridging ligands. The Co—Co bond happens to be robust and persists in all further transformations of the binuclear cation-radical (Nafady et al. 2006). [Pg.33]

When (40) is irradiated by Hg lamp at room temperature in the presence of pentamethyl-cyclopentadienyl dicarbonyl cobalt(III), Co(III) dithiolato complexes (45) and (46) are formed implying involvement of benzonitrile sulfide as an intermediate <92CL243). Thermolysis of (40) (and its phenyl ring substituted derivatives (40a)) at 110-140 °C in aromatic solvents results in formation of another heterocyclic mesoionic structure (47) and appears to proceed as a radical process (Scheme 2) (91TL4023). The reaction is inhibited by radical scavengers. [Pg.442]

In 1971 we succeeded, again for the first time, in transferring a carbene ligand from one metal atom to another (26, 47). For example, if one irradiates a solution of cyclopentadienyl(carbonyl) [methoxy (phenyl) carbene]-nitrosylmolybdenum(O) in the presence of an excess of pentacarbonyliron, one obtains tetracarbonyl[methoxy (phenyl) carbene]iron(0) with the simultaneous formation of cyclopentadienyl (dicarbonyl) nitrosylmolyb-denum ... [Pg.7]

Cyclopentadienyl dicarbonyl ruthenium dimer 132 reacts with silver tetrafluoroborate and diphenylacetylene to afford the cyclobutadiene ruthenium complex 133 (Scheme 12). Irradiation of 133 in dichloro-methane in the presence of several alkynes leads to the arene cyclopentadienyl ruthenium complexes 125 in high yield. This reaction appears to be a general route to sterically crowded ruthenium arene cations (55). [Pg.188]
