Multimetallic Uranium Nitride Cubane Clusters from Dinitrogen Cleavage

Rosario Scopelliti, Marinella Mazzanti, Farzaneh Fadaei Tirani, Ivica Zivkovic, Mikhail Batov

Dinitrogen cleavage provides an attractive but poorly studied route to the assembly of multimetallic nitride clusters. Here, we show that the monoelectron reduction of the dinitrogen complex [{U(OC6H2-Bu-3(t)-2,4,6)(3)}(2)(mu-eta(2):eta(2)-N-2)], 1, allows ...

A MOF-Based Spatial-Separation Layer to Enable a Uniform Favorable Microenvironment for Electrochemical CO2 Reduction

Jian Li

Regulating the local microenvironment of active sites to increase their specific CO2 concentration and pH gradient, is a promising approach to optimize the electrochemical CO2 reduction reaction (eCO(2)RR). However, currently reported morphological strateg ...

Two-Carbon Ring Expansion of Cyclobutanols to Cyclohexenones Enabled by Indole Radical Cation Intermediate: Development and Application to a Total Synthesis of Uleine

Qian Wang, Jieping Zhu, Alexandre Julien Florent Leclair

A single-electron transfer (SET) oxidation of indole or benzo[b]thiophene to a radical cation reverses the intrinsic polarity of these pi-excessive bicyclic heteroarenes. Here we report an oxidative two-carbon homologation of cyclobutanols to cyclohexenone ...
