Abstract
The borylation substitution of alkyl halides with diboron reagent proceeded in the presence of a copper(I)/Xantphos catalyst and a stoichiometric amount of K(O-t-Bu) base. The borylation proceeded with normal and secondary alkyl chlorides, bromides, and iodides, but alkyl sulfonates did not react. Menthyl halides afforded the corresponding borylation product with excellent diastereoselectivity, whereas optically active (R)-2-bromo-5-phenylpentane gave a racemic product. The reaction with cyclopropylmethyl bromide resulted in ring-opening products, suggesting that the reaction involves a radical-mediated mechanism.

Our group previously reported that a 4-silyl-3-butenyl methanesulfonate gave a cyclobutylboronate product under copper(I)-catalyzed conditions in the presence of diboron, in which no simple substitution product was detected.
Copper(II) salt was most probably reduced to copper(I) at the initial step of the catalysis
