By using ethylenediamine (En) as a complexing agent, the impact of various Zn2+ coordinated configurations on Zn anode reversibility was systematically studied. With the predominant configurations of [Zn(En)]2+ and [Zn(En)2]2+ in the electrolyte, both symmetric Zn/Zn cells and Zn/NiHCF full cells exhibit significantly improved cycling stability compared to the counterparts with pure ZnSO4 electrolyte.

A carbene-catalyzed cascade reaction is developed for the synthesis of multi-substituted indane derivatives. The reaction involves two sequential Michael-addition steps, of which the first step is enabled by an NHC-mediated radical process. This work demonstrates the synthetic potentials of NHC-mediated single-electron-transfer processes for efficient reactions and rapid synthesis. [ABSTRACT FROM AUTHOR]

A novel, mild, robust catalyst Y(OTf)3for C–C bond heterolysis of N-tosyl aziridines was developed and the resulting metallo-azomethine ylides may readily undergo [3+2] dipolar cycloaddition with an electron-rich olefin viaa stepwise reaction pathway with high regio- and diastereoselectivity leading to substituted pyrrolidines.

A novel catalytic exo/endoselectivity-controllable tandem heterocyclization/formal [4+3] cycloaddition was developed, which provides rapid, efficient and stereoselective access to highly fused polyheterocycles from readily available 2-(1-alkynyl)-2-alken-1-ones and 1,3-diphenylisobenzofuran under mild conditions.
