Ring-Size Effects in the Neophyl Rearrangement. VII.1 The Peroxide-Induced Decarbonylation of (1-Phenylcyclopropyl)- and (1-Phenylcyclobutyl)acetaldehydes
centered around ring-opening carbon–carbon bond cleavage/fluorination of strained cycloalkanols, either using precious silver catalysis or superstoichiometric ceric ammonium nitrate (CAN). Careful study of these methods has allowed us to design and develop a general Earth-abundant-element-catalyzed method for remotely fluorinated ketone synthesis via C–C bond cleavage. Critically, the use of manganese

A manganese-catalyzedelectrochemicaldeconstructivechlorination of cycloalkanols has been developed. This electrochemical method provides access to alkoxyradicals from alcohols and exhibits a broad substrate scope, with various cyclopropanols and cyclobutanols converted into synthetically useful β- and γ-chlorinated ketones (40 examples). Furthermore, the combination of recirculating flow electrochemistry

transition-metal-free nitrogen insertion provides access to a variety of medicinally relevant heterocycles such as pyrrolidenes, quinolines, and benzazepines (24 examples). Furthermore, combination with a photochemical Norrish–Yang-type cyclization allows an unprecedented access to indoles from ortho-substituted acetophenones.
