摘要: Abstract Reactions of [RuHCl(CO)(PPh3)3] with NaBmR (BmR = bis(2-mercapto-1-arylimidazolyl)borates, R = 4-chloro-phenyl; 4-methyl-phenyl; 4-nitro-phenyl) in refluxing THF afforded hydrido ruthenium complexes [RuH(CO)(PPh3)(κ3-H,S,S′-BmR)] (1–3). Treatment 1 chloroform gave chloride complex [RuCl(CO)(κ3-H,S,S′-BmR)(PPh3)] (4). Interactions Br2 or I2 at room temperature led to isolation bromide [RuBr(CO)(κ3-H,S,S′-BmR)(PPh3)] (5) and iodide [RuI(CO)(κ3-H,S,S′-BmR)(PPh3)] (6), respectively. Complexes 1–6 were characterized by microanalyses, IR, (1H, 11B, 13C, 31P) NMR spectroscopies. The molecular structures 1, 2, 5, 6 have been determined single-crystal X-ray diffraction.
