一些锇烯基卡拜配合物的合成及其金属有机化学性质研究

doi:10.6023/cjoc201305046

摘要/Abstract

OsH₂Cl₂(PCy₃)₂ (1)与炔丙醇HC≡CC(OH)Ph₂在室温及加热条件下反应可分别生成原子氢配位的γ-羟基卡拜配合物OsHCl₂[≡CCH₂C(OH)Ph₂](PCy₃)₂ (2)和原子氢配位的烯基卡拜OsHCl₂(≡CCH=CPh₂)(PCy₃)₂ (3). 2和3在氯化氢乙醚溶液作用下可转化为三氯配位的烯基卡拜OsCl₃(≡CCH=CPh₂)(PCy₃)₂ (4). 也可通过OsH₂Cl₂(PCy₃)₂与HC≡CC(OH)Ph₂在氯化氢乙醚溶液存在下反应, 由一锅法直接合成烯基卡拜配合物4. 化合物4还可通过OsCl₃(≡CCH=CPh₂)(PPh₃)₂ (5) 与PCy₃的配体取代反应来制备, 在反应过程中可分离到单个PPh₃配体被PCy₃取代的产物OsCl₃(≡CCH=CPh₂)(PCy₃)(PPh₃) (6). 化合物4可与水及吡啶发生配体取代反应, 分别生成水或吡啶配位的单膦卡拜配合物OsCl₃(≡CCH=CPh₂)(PCy₃)(S) (S=H₂O, 7; S=Py, 8). 此外, 4与NaOEt在室温下反应可得到锇烯基卡宾配合物OsCl₂(=CHCH=CPh₂)(PCy₃)₂ (9), 而与EtOH需在加热条件下才可反应, 生成的是原子氢卡拜3. 化合物9在溶液中不稳定, 可完全转化为热力学稳定的原子氢配位的卡拜3.

Reactions of the dihydride complex OsH₂Cl₂(PCy₃)₂ (1) with HC≡CC(OH)Ph₂ at room temperature or under heating condition produce the hydride hydroxycarbyne complex OsHCl₂[≡CCH₂C(OH)Ph₂](PCy₃)₂ (2) and the hydride alkenylcarbyne complex OsHCl₂(≡CCH=CPh₂)(PCy₃)₂ (3), respectively. Treatment of 2 or 3 with HCl·Et₂O affords the trichlorocarbyne complex OsCl₃(≡CCH=CPh₂)(PCy₃)₂ (4), which can be conveniently synthesized by the one pot reaction of 1 with HC≡CC(OH)Ph₂ in the presence of HCl·Et₂O. Complex 4 can be alternatively prepared from the phosphine ligand substitution of the trichlorocarbyne complex OsCl₃(≡CCH=CPh₂)(PPh₃)₂ (5) with PCy₃, from which the mono-substituted intermediate OsCl₃(≡CCH=CPh₂)(PCy₃)(PPh₃) (6) can be isolated. Complex 4 undergoes ligand substitution reactions with water and pyridine leading to the formation of the aqua and pyridine-coordinate mono phosphine carbyne complexes OsCl₃(≡CCH=CPh₂)(PCy₃)(S) (S=H₂O, 7; S=Py, 8). In addition, complex 4 reacts with NaOEt at room temperature to produce the alkenylcarbene complex OsCl₂(=CHCH=CPh₂)(PCy₃)₂ (9), which is unstable in solution and evolves into the thermally more stable hydride carbyne complex 3. In contrast, the reaction of 4 with EtOH can only take place at elevated temperature to give the hydride carbyne 3.
