A recyclable protocol using a CeO-nanorod catalyst for borylation of alkyl halides with Bpin (pin = OCMeCMeO) is reported. A wide range of synthetically useful alkyl boronate esters are readily obtained from primary and secondary alkyl electrophiles, including unactivated alkyl chlorides, demonstrating broad utility and functional group tolerance. Preliminary investigation revealed an involvement of in situ formed catalytically active boryl species.
