Deoxyfluorination of alcohols with aryl fluorosulfonates

Aryl fluorosulfonates is developed as a deoxyfluorinating reagent in the transformation of primary and secondary alcohols into the corresponding alkyl fluorides. These reagents are featured by easy availability, low-cost, high...

Synthesis of tertiary alkyl fluorides and chlorides by site-selective nucleophilic ring-opening reaction of α-aryl azetidinium salts

Site-selective nucleophilic ring-opening of 2 with Bu4NX proceeded at a much-substituted 2-position preferentially and produced tertiary alkyl halides 3.
