    Description / Table of Contents: H—C Bond Cleavage in Aldehydes by Neopentylruthenium(II) ComplexesNeopentylruthenium complexes of the type (η5-Cp)(L1)(L2)RuCH2CMe3 (1: Cp = C5Me5, L1 = L2 = PMe3; 3, 9, 10 and 11: Cp = C5H5, L2 = PPh3, L1 = PMe3, PMePh2, PMe2Ph and P(OMe)3, respectively) react with benzaldehyde with H—C bond cleavage of the aldehyde function to give the (η5-Cp)(L1)(L2)Ru benzoyl compounds 4, 13-16 and as the result of subsequent decarbonylation the (carbonyl) phenylruthenium complexes 2, 5, 12, 17-19 or mixtures thereof. Para phthaldialdehyde reacts with 1 (ratio 1 : 2) via the carbonyl complex 20 to give the 1,4-bis(ruthenium)benzene compound 21. Aliphatic aldehydes behave similarly: isobutyraldehyde reacts with 3 to give a mixture of the acyl-(22) and alkyl(carbonyl)ruthenium compound 23. 1 reacts with ferrocenealdehyde to give the carbonyl(ferrocenyl)ruthenium complex 25. The molecular structures of 22 and 2 as representatives of acyl- and (carbonyl)organylruthenium complexes, have been determined by X-ray diffraction.
    Notes: Die Neopentylruthenium-Komplexe vom Typ (η5-Cp)(L1)(L2)RuCH2CMe3 (1: Cp = C5Me5, L1 = L2 = PMe3; 3, 9, 10 und 11: Cp = C5H5, L2 = PPh3, L1 = PMe3, PMePh2, PMe2Ph bzw. P(OMe)3) reagieren mit Benzaldehyd unter H—C-Bindungsspaltung an der Aldehydgruppe und anschließender Decarbonylierung zu den entsprechenden Phenylruthenium-Verbindungen (η5-Cp)(CO)(L1)RuPh 2, 5, 12, 17-19 oder zu Mischungen dieser Komplexe mit den Benzoylruthenium-Verbindungen (η5-Cp)(L1)(L2)RuC(O)Ph 4, 13-16, den Vorstufen der Decarbonylierung. Para-Phthaldialdehyd reagiert mit 1 (Verhältnis 1 : 2) über den Carbonylkomplex 20 zum 1,4-Bis(ruthenium)benzol 21. Aliphatische Aldehyde verhalten sich ähnlich wie aromatische, Isobutyraldehyd bildet mit 3 eine Mischung von Acyl- (22) und Alkyl(carbonyl)ruthenium-Verbindung 23. 1 reagiert mit Ferrocenaldehyd zum Carbonyl(ferrocenyl)ruthenium-Komplex 25. Für 22 und 2 als Vertreter der Acyl- und der (Carbonyl)phenylruthenium-Komplexe wurden die Molekülstrukturen röntgenographisch bestimmt.

    Description / Table of Contents: H — C Bond Cleavage in Ferrocene by Organylruthenium ComplexesCp*(Me3P)2RuCH2CMe3 (1) reacts at 85°C with ferrocene (2) by cleavage of one H—C bond in 2 to give CpFe[η5-C5H4Ru(PMe3)2Cp*] (3) (Cp = η5-C5H5; Cp* = η5-C5Me5) and neopentane. The ruthenium atom in 3 has a distorted tetrahedral geometry, the planar Cp ligands in the ferrocenyl fragment are eclipsed. Solutions of 3 in [D6]benzene or [D8]THF exhibit H—D exchange of the ferrocenyl protons. In the [D8]THF molecule only the α-deuterium atoms are exchanged. Reaction pathways for this exchange are discussed.
    Notes: Cp*(Me3P)2RuCH2CMe3 (1) reagiert bei 85°C mit Ferrocen (2) unter Spaltung einer H—C-Bindung in 2 zu CpFe[η5-C5H4Ru(PMe3)2Cp*] (3) (Cp = η5-C5H5; Cp* = η5-C5Me5) und Neopentan. In 3 ist das Rutheniumatom verzerrt tetraedrisch koordiniert, und beide planaren Cp-Liganden im Ferrocenylteil sind ekliptisch angeordnet. Bei Lösungen von 3 in [D6]Benzol oder [D8]THF beobachtet man einen H—D-Austausch der Ferrocenylprotonen. Beim [D8]THF werden nur die α-Deuteriumatome ausgetauscht. Reaktionswege dieses Austauschs werden diskutiert.
