This nanocatalyst provides practical access to alkylboronate esters at room temperature in 1 h, with good functional group tolerance. The procedure is also applicable to the borylation of benzyl chlorides and bromides. Radical clock experiments suggest that the reaction involves a radical pathway. The catalyst can be recycled up to ten runs without appreciable loss in the activity. In addition, we demonstrated the use of this supported copper catalyst for the anti-Markovnikov-selective hydroboration of vinylarenes and borylation of aryl halides with B2pin2, providing alkyl- and arylboronate esters, respectively, in good to excellent yields. � 2023 The Royal Society of Chemistry.en-USCarbon nanotubesCatalyst supportsChlorine compoundsCopperDoping (additives)EstersMetal halidesSynthesis (chemical)A-carbonAlkylhalidesArylboronatesBorylationCopper catalystCopper nanoparticlesEfficient synthesisFacile synthesisNano-catalystNitrogen doped carbon nanotubesNanocatalystsArticlehttp://xlink.rsc.org/?DOI=D2CY01741E
