  Structural and two-dimensional phosphorus-31 nuclear magnetic resonance studies of derivatives from (RP)₅(R = Et or Ph) and activated triosmium clusters [Os₃(CO)₁₀X₂](X =µ-H or NCMe)

  摘要：

  The reaction of the cyclophosphane (EtP)(5) with the activated triosmium cluster [Os-3(mu-H)(2)(CO)(10)] at 80 degrees C gave [Os-3(mu-H)(CO)(8)(mu-eta(3)-P(5)Et(5)H)] 1 and [Os-3(CO)(10){1,3-(PEt)(5)}] 2. The compound (PhP)(5) reacted with [Os-3(mu-H)(2)(CO)(10)] at room temperature to give [Os-3(mu-H)(CO)(8)(mu-eta(3)-P(5)Ph(5)H)] 3. Treatment of (EtP)(5) with [Os-3(CO)(10)(NCMe)(2)] at room temperature afforded [Os-3(CO)(10){1,2-(PEt)(5)}] 4, while the reaction at 80 degrees C yielded only 2. All the reaction products have been characterized by elemental analysis and IR, H-1 and P-31 NMR spectroscopy. The solid-state structures of compounds 1, 2 and 4 established by single-crystal X-ray diffraction showed that the phosphorus ring in ! has undergone one P-P bond cleavage while those in 2 and 3 are intact. The solution structure of 3 has been fully characterized by two-dimensional P-31 NMR spectroscopy.

  pentaethylcyclophosphine, (EtP)5, with triosmium cluster [Os3(CO)10(NCMe)2] in dichloromethane at room temperature afforded [Os3(CO)101,2-(EtP)5}] (1) with an unusual 1,2-chelation mode for the cyclophosphine. The same reactants at a higher temperature gave rise to [Os3(CO)101,3-(EtP)5}] (2). Treatment of the same ligand with triosmium cluster [Os3(CO)11(NCMe)] yielded several new clusters [Os3(CO)11(EtP)5}] (3)

  摘要 五乙基环膦 (EtP)5 与三锇簇 [Os3(CO)10(NCMe)2] 在二氯甲烷中在室温下反应得到 [Os3(CO)101,2-(EtP)5}] (1)环膦具有不寻常的 1,2-螯合模式。相同反应物在较高温度下生成 [Os3(CO)101,3-(EtP)5}] (2)。用三锇簇 [Os3(CO)11(NCMe)] 处理相同的配体产生了几个新的簇 [Os3(CO)11(EtP)5}] (3), [Os3(CO)11}21, 3-(EtP)5}] (4), [Os3(CO)11}21,,2-(EtP)5}] (5), [Os3(CO)101,2,3- (EtP)5}Os3(CO)11] (6) 和 [Os3(CO)101,2,4-(EtP)5}Os3(CO)11] (7)。
