A copper-catalyzed coupling reaction between flow-generated unstabilized diazo compounds and terminal alkynes provides di- and trisubstituted allenes. This extremely mild and rapid transformation is highly tolerant of several functional groups.

Oomycetes in the genus Phytophthora are among the most damaging plant pathogens worldwide. Two important species are Phytophthora cinnamomi, which causes root rot in thousands of native and agricultural plants, and Phytophthora agathidicida, which causes kauri dieback disease in New Zealand. As is the case for other Phytophthora species, management options for these two pathogens are limited. H...

Lichtenegger et al. (1) demonstrated the fascinating occurrence of a copper biomineral in a worm jaw, but did not show, as they claimed, that this mineral has a structural role. Lichtenegger et al. based that conclusion on an apparent correlation between slight variations in mechanical properties and the measured chlorine content of the tested regions (the identified mineral, atacamite, contain...

Since the discovery of high transition-temperature (high Tc ) superconductivity in layered copper oxides [1], they have held the pole position in the race for achieving higher Tc [2]. In this race many different compounds which contain copper oxide layers has been examined. Although there are reports of Tc s up to 185K for very rare phases of complex compounds like (Sn1.0Pb0.5In0.5)Ba4Tm5Cu7O20...

Using copper complexes with an axially chiral bipyridine ligand C4-ACBP as the catalyst, an enantioselective functionalization of indoles with diazo compounds was developed with up to 95% ee. This protocol paves the way for further applications of these ligands.
