合成由五齿配体H 2 BA R TPP负载的镍配合物[Ni(H 2 BA R TPP)](ClO 4)2(R = Ph表示1或i Pr表示2),并氧化形成Ni III物种具有N3S2配位环境以模仿氧化态的镍超氧化物歧化酶(NiSODox)的活性位点。Ni III物种2 +表现出与 NiSODox相似的g值分别为2.15、2.12和2.02的菱形信号。DFT计算显示2 +具有不成对的电子,主要位于Ni III中心的d轨道,该电子与H 2 BA Pr TPP的轴向吡啶氮的p z轨道强烈重叠。

A Robust, Eco‐Friendly Access to Secondary Thioamides through the Addition of Organolithium Reagents to Isothiocyanates in Cyclopentyl Methyl Ether (CPME)
The nucleophilic addition of widely available and variously functionalized organolithiumreagents to isothiocyanates represents a straightforward, high‐yielding, one‐pot method to access secondary thioamides. The simple reaction conditions required and the broad scope (>50 cases examples) makes it a robust and reliable method to access both simple and complex thioamides, including enantiopure ones
