Silica-copper catalyst interfaces enable carbon-carbon coupling towards ethylene electrosynthesis

Michael Graetzel, Dan Ren, Yelin Hu, Jun Li, Reza Zamani, Xiaoyan Wang, Ziyun Wang, Yi Xu

Membrane electrode assembly (MEA) electrolyzers offer a means to scale up CO2-to-ethylene electroconversion using renewable electricity and close the anthropogenic carbon cycle. To date, excessive CO2 coverage at the catalyst surface with limited active si ...

Isolation and characterization of diazoolefins

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Zhaowen Dong, Paul Varava

Diazoolefins tend to be highly reactive compounds that rapidly lose dinitrogen. So far, most experimental evidence for diazoolefins is indirect, via trapping experiments. Here we show that diazoolefins are observed to form in reactions of N-heterocyclic ol ...

C-C bond activation enabled by dyotropic rearrangement of Pd(iv) species

Qian Wang, Jieping Zhu, Hua Wu, Jian Cao

The weak carbon-metal bond combined with the kinetic inertness of the carbon-carbon bond renders metal-catalysed C-C bond activation to be highly challenging. Most of the reported C-C bond activation methodologies involve strain-releasing cleavage of small ...

Palladium-Catalyzed Multicomponent Synthesis of Fully Substituted Alkylidene Furanones

Qian Wang, Jieping Zhu, Ruben Omar Torres Ochoa, Angel Renteria Gomez

In the presence of a catalytic amount of Pd(OAc)(2) and XantPhos, the three-component reaction of ynones, imines, and aryl iodides affords fully substituted alkylidene-furan-3(2H)-ones via a sequence of the Mannich reaction followed by chemo- and regiosele ...

Copper-Catalyzed Cyanoalkylative Aziridination of N-Sulfonyl Allylamines

Qian Wang, Jieping Zhu, Minh Tu Ha, Weisi Guo

Reaction of N-arylsulfonyl allylamines with alkyl nitriles in the presence of di-tert-butyl peroxide (DTBP) and a catalytic amount of copper salt afforded homologated aziridines in 43-86% yield. A sequence involving addition of the in situ generated cyanom ...

Synthesis and Structure-Activity Relationship Studies of C2-Modified Analogs of the Antimycobacterial Natural Product Pyridomycin

Stewart Cole, Ruben Hartkoorn, Anthony Vocat

A series of derivatives of the antimycobacterial natural product pyridomycin have been prepared with the C2 side chain attached to the macrocyclic core structure by a C-C single bond, in place of the synthetically more demanding enol ester double bond foun ...
