The stable complex [bis(toluene-3,4-dithiolato)copper(iii)][NEt3H] has been synthesised and characterised as a square-planar Cu(iii) complex by X-ray photoelectron spectroscopy, cyclic voltammetry and DFT calculations. Intriguingly, when fragmented in FTICR-MS, an unusual [(toluene-3,4-dithiolate)Cu(iii)(peroxide)]- complex is formed by reaction with oxygen. Natural 1,2-dithiolenes known to bind molybdenum might stabilise Cu(iii) in vivo.
已经通过 X 射线光电子能谱、循环伏安法和 DFT 计算合成并表征了稳定的配合物 [双（甲苯-3,4-二硫醇酸根合）铜（III）][NEt3H]，其为平面正方形的 Cu(iii) 配合物。有趣的是，当在 FTICR-MS 中碎片化时，配合物与氧反应生成了一种不寻常的 [(甲苯-3,4-二硫醇酸根合)Cu(iii)(过氧化物)]- 配合物。已知与钼结合的天然 1,2-二硫烯可能在体内稳定 Cu(iii)。
