fragmentation of cyclohexa-2,5-dien-1-yl-substituted acyl chlorides into a low-molecular-weight arene, carbon monoxide and HCl. In the presence of π-basic substrates such as alkenes and alkynes, HCl is transferred stepwise to afford the corresponding hydrochlorination products. The overall reaction is a decarbonylative transfer hydrochlorination driven by aromatization and carbon-monoxide release.
