Transition metal-mediated reductive coupling of diazoesters

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 2 intermed...

Description
Summary: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 2 intermediate, which induces significant radical character on the terminal nitrogen. The first transition-metal mediated reductive coupling of diazoesters is reported. The reaction proceeds via a 2 -coordinated intermediate, featuring significant radical character on the terminal nitrogen.
