with 2 gave two diastereomeric complexes, trans,cis-[RuCl2(DMSO)2(L1)] (3) and chiral cis,cis-[RuCl2(DMSO)2(L1)] (4). Reaction of 2 with 2-(2-formylhydrazino)-1,3,4-thiadiazole in MeOH gave the complex trans,cis-[RuCl2(DMSO)2(L2)] (5) with concomitant deformylation of the starting ligand. The process was catalyzed by RuII in very low yield. Synthesis of the Ru complexes of 4-amino-3-methyl-1,2,4-Δ2-triazoline-5-thione
研究了硫代碳酰肼的三唑、噻二唑和三唑啉衍生物对顺式-[RuCl2(DMSO)4] (2) 的化学行为。4-氨基-5-甲硫基-3-(2-吡啶基)-1,2,4-三唑 (L1) 与 2 反应得到两个非对映体复合物,反式,顺式-[RuCl2(DMSO)2(L1)] ( 3) 和手性顺式,顺式-[RuCl2(DMSO)2(L1)] (4)。2 与 2-(2-甲酰肼基)-1,3,4-噻二唑在 MeOH 中的反应得到络合物反,顺-[RuCl2(DMSO)2(L2)](5),同时起始配体发生去甲酰化。该过程由 RuII 催化,产率非常低。4-amino-3-methyl-1,2,4-Δ2-triazoline-5-thione (L3) 和 4-amino-3-ethyl-1,2,4-Δ2-triazoline-5 的 Ru 配合物的合成-硫酮 (L4) 导致 DMSO 促进金属发生有趣的氧化。2 与这些配体在
