olefins in water using methylene blue as photoredox catalyst and persulfate as oxidant is reported. In this unprecedented unified approach, two different transformations are accomplished using only one set of reagents. The method has a broad scope spanning a range of aromatic and aliphatic aldehydes as well as conjugated and nonconjugated olefins to deliver ketones and epoxyketones from abundant and

for ketone synthesis. As an important coupling partner, bench-stable and commercially available alkyl boronicacids are widely used in transition metal catalysis, but they are rarely utilized as radical precursors for acylative coupling reactions. Herein, we reported an energy-transfer-enabled radical acylation using free alkyl boronicacids via NHC/photo dual catalysis. This protocol could efficiently
We develop herein an efficient rhodium-catalyzed remote isomerization of aromatic and aliphatic alkenyl alcohols into ketones. This catalytic process, with a commercially available catalyst and ligand ([RhCl(cod)]2 and Xantphos), features high efficiency, low catalyst loading, good functional group tolerance, a broad substrate scope, and no (sub)stoichiometric additive.
