Abstract The synthesis, spectroscopic properties and crystal structure of the novel complex fac-[RuCl2(DMSO-S)3(n-butylamine)] (DMSO-S = sulfur-bonded dimethylsulfoxide) have been reported. The coordination environment of the ruthenium atom is best described as a distorted octahedral, where three DMSO ligands occupy one face of the octahedron, while the two chlorido and the amine ligand occupy the other one. The catalytic activity of fac-[RuCl2(DMSO-S)3(n-butylamine)] was probed in two processes, ring-opening metathesis polymerization (ROMP) and atom-transfer radical polymerization (ATRP). The ROMP of norbornene (NBE) was carried out in the presence of ethyl diazoacetate (EDA) for 5 min at 50 °C which afforded yields around 80%. Poly(norbornadiene) was only produced by photoinduced ROMP leading to 27% yield. The catalytic activity for ATRP of methyl methacrylate (MMA) and styrene (St) for 8 h resulted in 88 and 33%, respectively.

fac-[RuCl2(DMSO-S)3(n-丁胺)]：合成、结构表征和双催化性能

摘要 已经报道了新型复合 fac-[RuCl2(DMSO-S)3(n-丁胺)] (DMSO-S = 硫键二甲基亚砜) 的合成、光谱性质和晶体结构。钌原子的配位环境最好被描述为扭曲的八面体，其中三个 DMSO 配体占据八面体的一个面，而两个氯化物和胺配体占据另一个面。fac-[RuCl2(DMSO-S)3(n-丁胺)]的催化活性在两个过程中被探测，开环易位聚合(ROMP)和原子转移自由基聚合(ATRP)。降冰片烯 (NBE) 的 ROMP 在重氮乙酸乙酯 (EDA) 存在下在 50°C 下进行 5 分钟，产率约为 80%。聚（降冰片二烯）仅通过光诱导的 ROMP 产生，产率为 27%。
