A novel electrochemical dehydrogenative cyclization/aromatization of aniline-tethered alkylidenecyclopropanes enabled by N–H/C–H functionalization is described.
Fluorohydrins, fluoroethers, fluoroesters and fluoroketones were synthesized via fluorination of alkylidenecyclopropanes and alkylidenecyclobutanes with selectfluor.
A palladium-catalyzed stereospecific ring-opening arylation of α-aminoaryl-tethered alkylidenecyclopropanes for the stereoselective synthesis of 1,1,2-trisubstituted conjugated dienes has been developed.
An unconventional radical-type migratory insertion mechanism was identified, leading to a distinct cobalt-catalyzed radical-mediated carbon–carbon cleavage for alkylidenecyclopropanes.
Metal catalyzed hydroarylation reactions achieve C–C or C-heteroatom bonds in an atom economical and step economical manner. Here we cover the literature from 2016 to 2022 to summarize the recent advancements in Ru-catalyzed hydroarylation reactions of alkenes and alkynes.
