- W2047893506 abstract "Der Komplex C5H5Co(PMe3)2 (1) reagiert mit sekundären und tertiären Alkylhalogeniden RX (R CHMe2, CHe3, CMe2Et) zu den Kationen [(C5H4R) CoH(PMe3)2]+, die nach Reduktion mit NaH die Neutralverbindungen (C5H4Co(PMe3)2) (5–7) ergeben. Aus diesen werden die zweifach ringsubstituierten Komplexe [C5H3RR′)CoH(PMe3)2]PF6 (15–17), (C5H3RR′)Co(PMe3)2) (18–20) und [(C5H3RR′)CoCH3(PMe3)2] 1 (21–23) (R′ CHMe2, CMe3) Synthetisiert. In den Verbindungen mit R R′ CMe3 ist die Rotation um die Metall-Ring-Bindung so stark behindert, daß bei 25–100°C starre Konformere vorliegen. Für [C5H3(CHMe2CMe3]Co(PMe3)2 (19) ist unterhalb −10°C ebenfalls eine eingefrorene Konformation nachweisbar. Die Komplexe [C5H3(SiMe3)R)CoH(PMe3)2]PF6 (26–28), [C5H3(SiMe3)R)]CoH(PMe3)2 (27–29) (R H, CHMe2) und C5H5Co(PEt3)2 (10) werden ebenfalls dargestellt und ihr dynamisches Verhalten sowie ihre Reaktivität untersucht. Basic Metals, XXX. Reactivity and Dynamics of the Complexes C5H5Co(PR3)2 (R Me, Et), (C5H4R)Co(PMe3)2, and C5H3RR)Co(PMe3)2: Influence of Steric Effects on the Lewis Basicity of Electron-rich Metals The complex C5H5Co(PMe3)2 (1) reacts with secondary and tertiary alkyl halides RX (R CHMe2, CMe3. CMe2Et) to give the cations [(C5H4R)CoH(PMe3)2]+ which after reduction with NaH form the neutral compounds (C5H4R)Co(PMe3)2) (5–7). These are used as starting materials for the preparation of the disubstituted complexes [C5H3RR)CoH(PMe3)2]PF6 (15–17), (C5H3RR)Co(PMe3)2) (18–20) und [(C5H3RR)CoCH3(PMe3)2] 1 (21–23) (R CHMe2, CMe3). In the compounds with R R CMe3 rotation about that metal-ring bond is so hindered the rigid conformers are present at 25–100°C. Similarly, a frozen conformation of the complex [C5H3(CHMe2)CMe3]Co(PMe3)2 (19) is evident below −10°C. The preparation of the complexes [C5H3RR)CoH(PMe3)2]PF6 (26–28), [C5H3(SiMe3)R]Co(PMe3)2 (27–29) (R H, CHMe2) and C5H5Co(PEt3)2 (10) is also described and their dynamics as well as their reactivity are investigated." @default.
