Abstract: Abstract Hexavalent chromium (Cr(VI)) is a widespread, toxic contaminant in the environment. Owing to the increasingly strict requirements for green production and pollution emission, Cr(VI) generation via Cr(III) oxidation is gradually becoming the primary source… read more here.

Abstract: Phosphoranyl radicals are essential mediators to bring about new radicals but often produce a stoichiometric amount of phosphine oxide/sulfide waste. Herein, we devised a phosphorus-containing species as a radical precursor, but without the generation of… read more here.

DOI: 10.1021/acs.orglett.7b02983
Abstract: An efficient synthesis of disubstituted acrylic acids has been realized via Rh(III)-catalyzed C-H activation of (hetero)arenes and coupling with four-membered methyleneoxetanones under redox-neutral conditions. In most cases, the reactions are silver-free, and the products are… read more here.
