2‐Aryl‐substituted cyclopropyl aldehydes undergo an unprecedented Au nanoparticle‐catalyzed silaboration leading to rearranged linear b‐ boronate‐bearing silyl enol ethers. Formation of these products is attributed to the ring opening radical clock rearrangement of the intermediate a ‐cyclopropyl radical into a benzyl radical.
