✦ Synopsis
Reaction of the sodium metalates Na[M(CO) 2 C 5 R 5 ] [M = Fe, fragment chlorination of 3a-c with CCl 4 or HCCl 3 occurs at the α-silicon to give C 5 R 5 (OC) 2 M-SiCl 2 -SiH 3 (4a-c). The R = H (1a), Me (1b); M = Ru, R = H (1c), Me (1d)] with an equimolar amount of hexachlorodisilane yields the metallo-metallo-disilanes were characterised by 1 H-, 13 C-, 29 Si-NMR, IR and especially Raman spectroscopy. The structures of pentachlorodisilanes C 5 R 5 (OC) 2 M-SiCl 2 -SiCl 3 (2a-d), which can be converted into the pentahydrido analogues C 5 H 5 (OC) 2 Fe-Si 2 Cl 5 (2a) andC 5 Me 5 (OC) 2 Fe-Si 2 H 5 (3b) have been determined by X-ray analysis; 2a,b, 3a,b were C 5 R 5 (OC) 2 M-SiH 2 -SiH 3 (3a-c) via Cl/H exchange with LiAlH 4 . Due to the activating effect of the transition metal theoretically described by DFT calculations.
