  摘要：

  Compounds of the general form Ru-2(CO)(4)(eta(5),eta(5)-C(5)H(4)LC(5)H(4)), where L = CH2-, (CH3)(2)C-, C2H4- and (CH3)(2)Si-, have been found to undergo photolysis in deuterobenzene or deuterotoluene to give 'twisted' ruthenium hydride complexes of the form [Ru(CO)(2)][Ru(CO)(2)H](eta(5),eta(5):eta(1)-C(5)H(4)LC(5)H(3)). Reaction of these hydrides with chlorocarbons resulted in the formation of the corresponding chlorides which could be isolated and characterized by IR, H-1 and C-13 NMR, mass spectrometry, and elemental analysis. In the particular case of Ru-2(CO)(4)[eta(5),eta(5)-C5H4(CH3)(2)SiC5H4] a secondary photochemical reaction occurs with formation of [Ru(CO)(2)](2)(mu-eta(5):eta(1)-C5H4)[mu-(CH3)(2)Si-(eta(5)-C5H4)] in which Ru-Ru and Cp-Si bonds have been broken and new Ru-Cp and Ru-Si bonds formed. The molecular structure of [Ru(CO)(2)][RU(CO)(2)Cl](eta(5),eta(5):eta(1)-C5H4CH2C5H3) was determined by X-ray crystallography:monoclinic, Cc, a = 27.636(5) Angstrom, b = 9.058(2) Angstrom, c = 14.545(5) Angstrom, beta = 120.85(3)degrees, V = 3126(2) Angstrom(3), Z = 8, R(F)= 2.29%.

  Photolysis of the doubly bridged dicyclopentadienyl dimethyl dinuclear complexes [(eta(5)-C5H2R)(2)(SiMe2)(2)]-M-2(CO)(4)Me-2 (M = Ru, R = H (2a), Bu-t (2b); M = Fe, R = H (2c)) in benzene yields the corresponding methylene-bridged complexes [(eta(5)-C5H2R)(2)(SiMe2)(2)]M-2(CO)(2)(mu-CO)(mu-CH2) (3a-c) and the M-M-bonded complexes [(eta(5)-C5H2R)(2)(SiMe2)(2)]M-2(CO)(4) (1a-c). Irradiation of the analogous diethyl complex [(eta(5)-C5H2R)(2)(SiMe2)(2)]Ru-2(CO)(4)Et-2 (4) affords only 1a. Unlike the case for the doubly bridged complexes, photolysis of the singly bridged dicyclopentadienyl dimethyl diruthenium complexes [(eta(5)-C5H4)(2)(EMe2)]Ru-2(CO)(4)Me-2 (E = C (5a); E = Si (5b)) in benzene yields the corresponding "twisted" ruthenium methyl complexes with a cyclopentadienyl Ru sigma bond (eta(5),eta(5):eta(1)-C5H4(EMe2)C5H3)[Ru(CO)(2)][Ru(CO)(2)Me] (6a,b) and the similar phenyl complexes (eta(5),eta(5):eta(1)-C5H4(EMe2)C5H3)[Ru(CO)(2)][Ru(CO)(2)Ph] (7a,b), from reaction with the benzene solvent. Plausible mechanisms for the formation of the different types of products are proposed involving intramolecular C H bond activation. The molecular structures of 2a,c, 3a,c, 4, 5a, 6a, and 7h, determined by X-ray diffraction, are also presented.
