  摘要：

  The reaction of RuCl2(PPh3)(3) with HSiX3 in benzene produced (eta(6) -benzene)Ru(PPh3)(SiX3)(2) (SiX3 = SiCl3 (1), SiMeCl2 (2)) as white to light yellow solids in high yields (>80%). A mixture of (eta(6)-benzene)Ru(PPh3)(SiMe2Cl)(2) (3), (eta(6) -benzene)Ru(PPh3)(SiMe2Cl)(SiMeCl2) (4), and 2, due to silicon substituent redistribution, was obtained from the reaction of RuCl2(PPh3)(3) with HSiMe2Cl in benzene. (eta(6) -benzene)Ru(PPh3)(SiMe3)2 (5) was prepared by the methylation of 1, 2, or the 3/4 mixture with AlMe3. The related complexes (eta(6)-arene)Ru(PPh3)-(SiMeCl2)(2) (arene = toluene (6), o-xylene (7), m-xylene (8), p-xylene (9), mesitylene (10), anisole (11)) were obtained from the reaction of RuCl2(PPh3)(3) with HSiMeCl2 in the corresponding arene solvent at elevated temperature. Complexes 1, 2, and 5 were structurally characterized by single-crystal X-ray diffraction and exhibit a characteristic three-legged "piano-stool" geometry. The Ru-Si distances, in these complexes, ranged from 2.322 to 2.438 Angstrom; the Ru-Si distance increased as the number of methyl groups on silicon increased.
