Manganese-catalyzed C—C bond cleavage of cyclobutanols has attracted great attention due to the high abundance and cheap and eco-friendly behaviour. A manganese-catalyzed ring-opening C—C bond fluorination of cyclobutanols is reported. Under mild conditions, the reaction provides a straightforward access to γ-fluorinated ketones using 10 mol% Mn(OAc)2 as catalyst and electrophilic fluorination reagent, which was generated in situ from HF•Et3N and PhIO, as fluorine source. The reaction has an excellent functional-group tolerance and displays a broad substrate scope, affording the corresponding products in 50%~76% yields.

Key words: manganese catalysis, C—C bond functionalization, cyclobutanol, fluorination, γ-fluorinated ketone
