报道了第一过渡金属离子介导的重氮酯通过末端氮的还原偶联反应。所得到的四氮烯桥连的双（二氮烯基乙酸酯）作为一种新的双核配体的铁（III）。DFT计算表明，还原偶联通过κ2中间体发生，其在末端氮上诱导显著的自由基特征。
The first transition metal mediated reductive coupling of diazoesters through the terminal nitrogens is reported. The resulting tetrazene-bridged bis(diazenylacetate) serves as a novel dinucleating ligand to iron(III). DFT calculations suggest that the reductive coupling takes place via a κ2 intermediate, which induces significant radical character on the terminal nitrogen.
