A visible-light photoinduced fragmentation borylation of O-phthalimido cycloalkanols with bis(catecholato)diboron is described. Structurally diverse keto and formyloxy alkyl boronic esters are conveniently prepared by radical-mediated ring-opening of cyclic alcs. and hemiacetals, resp. The reactions proceed under mild conditions in the absence of additives or photocatalysts, display excellent functional group tolerance, and allow cleavage of 4-, 5-, 6-, and 7-membered ring substrates. The mechanism proceeds via sequential homolytic N-O and C-C bond cleavages, the latter of which involves β-scission of an alkoxy radical, generating a carbonyl and an alkyl radical that is trapped by the diboron reagent. Spectroscopic studies suggest direct photoexcitation of either the phthalimide or diboron substrates with blue-light can initiate a radical chain mechanism.
