A method for the synthesis of ketones from aldehydes and boronic acids via a transition-metal-free C-H functionalization reaction is reported. The method employs nitrosobenzene as a reagent to drive the simultaneous activation of the boronic acid as

We describe the first ring-opening of furfuryl alcohols with boronic acids to afford functionalized γ-ketoaldehydes. The transformation builds a new C-C bond at the original C-4 of the starting furan, and tolerates ring-substitution at C-3 and C-4 p
