A novel 1,3,4-substituted 1,2,3-triazolium salt was found to function as an effective precursor for the synthesis of the first structurally characterized cationic silver(I) and ruthenium(II)carbene complexes of overall 1:2 ligand-to-metal stoichiometry. The Ag(I) complex crystallized in the form of an eight silver atom-containing cluster, whereas the Ru(II) complex proved to be a discrete species and was found to be capable of initiating the ring-opening metathesis polymerization of norbornene upon activation with (trimethylsilyl)diazomethane.
一种新型的1,3,4-取代的1,2,3-三唑鎓盐被发现可作为一种有效的前体，用于合成首例结构表征的阳离子银（I）和钌（II）卡宾配合物，其配体与金属的化学计量比总体为1:2。银（I）配合物以含有八个银原子的簇的形式结晶，而钌（II）配合物被证明是一种离散物种，并且发现其在用（三甲基甲硅烷基）重氮甲烷活化后能够引发降冰片烯的开环易位聚合反应。
