  摘要：

  [RuCl 2（PPh 3）3 ]和哌啶（pip）之间的反应产生了新型[RuCl 2（PPh 3）2（pip）]络合物，该络合物通过开环易位聚合反应在不到1分钟的时间内定量聚合了降冰片烯（NBE）。在室温下，在5μL乙二唑乙酸盐存在下。一个中号瓦特/中号Ñ如果降冰片烯的量分几批加入到[NBE]获得的值1.05 /的[Ru] = 5.000。降冰片二烯在室温下以48％的收率聚合5分钟。在50°C下5分钟，前体复合物仅产生63％的聚降冰片烯和6％的聚降冰片二烯。31 P { 11 H NMR分析表明，新的络合物在溶液中不象在前体络合物的情况下那样发生二聚化。提出哌啶的存在适合于通过高活性的五配位单核Ru（II）配合物来提高反应速率和控制钌复分解催化。

• Benefits of donor solvents as additive on ROMP of norbornene catalyzed by amine Ru complexes

  With the aim of understanding the influence of donor solvents on the reactivity of the amine complexes [RuCI2(PPh3)(2)(piperidine)] (1) and [RuCI2(PPh3)(2)(imidazole)(2)] (2) in the presence of ethyldiazoacetate, and on the properties of the resulting polymer, a ring opening metathesis polymerization of norbornene was carried out in the presence of small amounts of common solvents such as additives (isopropanol, THF, N,N-dimethylformamide, 2,6-lutidine, isopropanethiol, acetonitrile, dimethyl sulfoxide, NEt3, NH2Me and pyridine). From observations, typical coordinating solvents like DMSO, NEt3, NH2Me and pyridine, hardly affected the yields when either complex was employed. With other additives, the major advantage was the decrease in the polydispersity indices. On using complex 1 with 2,6-lutidine, observed values of M-w/M-n were as low as 1.3, while the yield decreased from 99% to about 20-30% at RT for similar to 1 min in pure solution. In the case of complex 2, which is almost inactive to ROMP (19% at 50 degrees C for 5 min with M-w/M-n = 6.30), the yield was three-fold (60% at 50 degrees C for 5 min with M-w/M-n = 1.95) compared to that of without the Further, the M-w/M-n was observed to decrease to 1.34 with 200 eq. of THF.
