Palladium‐Catalyzed Gem‐Diborylalkylation of Silyl Enol Ethers and N‐Vinylacetamide via Diboryl Carbon‐Centered Radicals

Abstract Herein, a palladium‐catalyzed coupling of gem ‐iododiborylalkanes with electron‐rich olefins to access β,β‐diboryl ketones and aldehydes under mild conditions is reported. This method exhibits broad substrate scope and excellent functional group tolerance. Mechanistic studies support a distinctive pathway involving gem ‐diboryl carbon‐centered radicals and a Pd(0)/Pd(I) catalytic cycle, without the formation of Pd(II) intermediates. This protocol provides a new platform for accessing synthetically valuable gem ‐diboryl carbonyl compounds and expands the reactivity profile of organoboron‐based radical transformations.
