- W2040028246 abstract "Die Benzolosmium(0)-Verbindungen C6H6Os(CO)L [8: L = PiPr3; 9: L = P(OiPr)3; 10: L = P(OPh)3] werden durch Reduktion von [C6H6OsI(CO)L]PF6 (5–7) mit NaC10H8 in THF hergestellt. Bei der Protonierung von 8 und 9 mit NH4PF6 oder HBF4 entstehen die Hydridoosmium(II)-Komplexe [C6H6OsH(CO)L]X (11; 12a, b), die mit NaH wieder zu den Neutralverbindungen 8 und 9 reagieren. Der zu 11 und 12a analoge Carbonyl(ethylen)-hydridoosmium(II)-Komplex [C6H6OsH(CO)(C2H4)]PF6 (21a) bildet sich nahezu quantitativ bei der Umsetzung von C6H6Os(CH3)2(CO) mit [CPh3]PF6 und ergibt nach Deprotonierung mit NaH C6H6Os(CO)(C2H4) (22). Durch Reaktion von C6H6OsI2(CO) mit Methyllithium und von 21a mit NaI werden die Alkyl(iodo)osmium-Verbindungen C6H6OsCH3(CO)I (24) und C6H6OsC2H5(CO)I (23) erhalten. Ausgehend von C6Me6-RuCl2(CO) sind die Ruthenium-Komplexe [C6Me6RuCl(CO)2]-PF6 (15), C6Me6Ru(CO)2 (16) und C6Me6Ru(CH3)2(CO) (25) zugänglich. Arene(phosphane) metal Complexes, XV. – Synthesis of Neutral and cationic Arene(carbonyl)metal complexes of Ruthenium and Osmium with C6Me6Ru und C6H6Os as Building Block The benzeneosmium(0) compounds C6H6Os(CO)L [8: L = PiPr3; 9: L = P(OiPr)3; 10: L = P(OPh)3] are prepared by reduction of [C6H6OsI(CO)L]PF6 (5–7) with NaC10H8 in THF. Protonation of 8 and 9 with NH4PF6 or HBF4 gives the hydridoosmium(II) complexes [C6H6OsH(CO)L]PF6 (11; 12a, b) from which the neutral compounds 8 and 9 are regenerated with NaH. The carbonyl(ethylene)hydridoosmium(II) complex [C6H6OsH(CO)-(C2H4)]PF6 (21a), an analogue of 11 and 12a, is almost quantitatively obtained from C6H6Os(CH3)2(CO) and [CPh3]PF6; it gives C6H6Os(CO)(C2H4) (22) by deprotonation with NaH. Reactions of C6H6OsI2(CO) with methyllithium and of 21a with NaI lead to the formation of the alkyl(iodo)osmium compounds C6H6OsCH3(CO)I (24) and C6H6OsC2H5(CO)I (23), respectively. The synthesis of the ruthenium complexes [C6Me6RuCl(CO)2]PF6 (15), C6Me6Ru(CO)2 (16), and C6Me6Ru(CH3)2(CO) (25) has been achieved using C6Me6RuCl2(CO) as the starting material." @default.
