Catalysis by Activated Copper Sulphide

The influence of sulphide transport on the growth and properties of copper sulphide films on copper

Asymmetric catalysis activated by visible light.

Visible light driven organic chemistry has sparked much excitement over the last several years. This review summarizes recent progress in combining visible light activation with asymmetric catalysis, processes that are either mediated by photoinduced electron or energy transfer. The tasks of photoactivation and asymmetric catalysis are typically accomplished by dual catalyst systems but several...

Copper catalysis in organic synthesis

Copper is a very versatile transition metal that has been used as a building material by human civilizations for over 6000 years. Copper is also an essential element, responsible for important biological processes. The title of this Thematic Series published in the Beilstein Journal of Organic Chemistry is “Copper catalysis in organic synthesis”. A web of scienceTM topic search of “copper-catal...

Arylboration of alkenes by cooperative palladium/copper catalysis.

Arylboration of vinylarenes and methyl crotonate with aryl halides and bis(pinacolato)diboron by cooperative Pd/Cu catalysis has been developed, giving 2-boryl-1,1-diarylethanes and an α-aryl-β-boryl ester in a regioselective manner. The reaction is compatible with a variety of functionalities and amenable to be scaled-up to a gram scale with no detriment to the yield. A short synthesis of the ...

Colloidal synthesis and characterizations of wittichenite copper bismuth sulphide nanocrystals.

Wittichenite (Cu(3)BiS(3)) nanocrystals have been synthesized utilizing a hot-injection method. They have been characterized in detail. Cu(3)BiS(3) nanocrystals possessed a band gap of 1.56 eV, and the corresponding nanocrystal-film shows a clear photoresponse in I-V measurements. Our work illustrates that Cu(3)BiS(3) nanocrystals have potential in the application of solar cells.
