TL;DR: In this paper, the Darstellung von Ubergangsmetall-Komplexen nucleophiler Carbene wird beschrieben, and die Vorliegen von Carben-Liganden in den neuen Verbindungen, die uber ihr Carbenkohlenstoffatom komplex an das Metall gebunden sind, wird aus 1H-NMR and IR-spektroskopischen Untersuchungen gefolgert.
Abstract: Die Darstellung von Ubergangsmetall-Komplexen nucleophiler Carbene wird beschrieben. Metallcarbonyl-Verbindungen reagieren mit Lithiumorganylen unter nucleophiler Addition des organischen Restes am Kohlenstoffatom eines Kohlenmonoxid-Liganden. Die anionischen Komplexe (6–8) lassen sich mit Sauren am Sauerstoffatom des gebildeten”Acyl-Liganden” zu Alkyl-hydroxy- bzw. Aryl-hydroxy-carben-Komplexen (9–11) protonieren, die nut in sehr wenigen Fallen isolierbar sind. Sie zersetzen sich unter Entstehung von Aldehyden und Ruckbildung der eingesetzten Metallcarbonyl-Verbindungen. Eine Methylierung gelingt jedoch mit Diazomethan zu stabilen, ungeladenen, leicht fluchtigen, diamagnetischen Metallcarbonyl-carben-Komplexen (18–20). Das Vorliegen von Carben-Liganden in den neuen Verbindungen, die uber ihr Carbenkohlenstoffatom komplex an das Metall gebunden sind, wird aus 1H-NMR-und IR-spektroskopischen Untersuchungen gefolgert. Die rontgenographisch bewiesene Struktur (CO)5CrC(OCH3)C6H5 wird hinsichtlich der Bindungsverhaltnisse diskutiert.
