A series of 5-hydroxypentenes was synthesized from the reaction mixture of Mg powder, 1,2-dibromoethane, 4-bromobutene and aldehydes in THF under ultrasound. This sonochemicalBarbierreaction provides a simple and alternative method for preparation of 5-hydroxypentene instead of the allylating reagent with epoxide.
Here we disclose a general Co(II/III/IV) electrocatalytic platform for alkene functionalization. Driven by electricity, a set of the oxidative hydrofunctionalization reactions via hydrogen atom transfer were demonstrated without the need for stochiometric chemical oxidants. The scope of the reactions encompasses hydroalkoxylation, hydroacyloxylation, hydroarylation, semipinacol rearrangement, and deallylation

A novel, organocatalytic and environmentally friendly protocol for the synthesis of polysubstituted tetrahydrofurans from trivial starting materials is described. Employing a 2,2,2-trifluoroacetophenone-mediated oxidation, which utilizes H2O2 as the green oxidant,...
