An efficient method for the metal-free deaminative borylation of alkylamines, using bis(catecholato)diboron as the B source, to directly synthesize various alkyl K trifluoroborate salts is introduced. The key to this high reactivity is the use of pyridinium salt activated alkylamines, with a catalytic amount of a bipyridine-type Lewis base as a promoter. This transformation shows good functional-group compatibility (e.g., it is unimpeded by the presence of a ketone, indole, internal alkene, or unactivated alkyl chloride) and can serve as a powerful synthetic tool for borylation of amine groups in complex compounds Mechanistic experiments and computations suggest a mechanism in which the Lewis base activated B2cat2 unit intercepts an alkyl radical generated by single-electron transfer (SET) from a B-based reductant.
