derivatives via the Lewis or Brønsted acid catalysed cascade nucleophilic addition, electronic cyclization, ring-opening rearrangement of propargylic alcohol-tethered alkylidenecyclopropanes with indole and pyrrole derivatives. The reaction exhibited a broad substrate scope and good functional group tolerance under metal-free conditions, affording the desired products in moderate to good yields.

Deoxygenative Arylation of Carboxylic Acids by Aryl Migration
phosphoranyl radical chemistry allows for precise cleavage of a stronger C-O bond and formation of a weaker C-Cbond by 1,5-aryl migration under mild reaction conditions. This new protocol is independent of substrate redox-potential, electronic, and substituent effects. It affords a general and promising access to 60 examples of synthetically versatile o-amino and o-hydroxy diaryl ketones under redox-neutral

from the reaction of propargyl alcohol-tethered alkylidenecyclopropanes with iodine. The reaction proceeded through an iodination-initiated cascade intramolecular enyne cyclization and electrophilic aromatic substitution reaction process in 1,2-dichloroethane upon heating, giving desired spirocyclic products in moderate to excellent yields. Further transformation of the obtained products has also been
