Abstract Secondary alkyl chlorides have been efficiently prepared from secondary alkyl sulfonates under mild and user-friendly conditions. The exchange reaction was generally performed by using benzyltributylammonium chloride in acetone (reflux, 30 min). Yields are excellent from functionalized, base-sensitive and hindered secondary alkyl sulfonates. Secondary alkyl chlorides have been efficiently

A practical, high-yielding method for the deoxy-fluorination of alcohols is presented using AlkylFluor, a novel salt analogue of PhenoFluor. AlkylFluor is readily prepared on multigram scale and is stable to long-term storage in air and exposure to water. The practicality and applicability of this method is demonstrated with a variety of primary and secondary alcohol substrates.
