Having established optimal reaction conditions for the deoxygenative radical addition to gemdeborylalkene 2', we explored the scope of the transformation (Figure ). Various aromatic carboxylic acids 1a-1p possessing different functional groups gave the corresponding β-keto-gemdiborylalkanes products 3a-3p in moderate to good yields. This deoxygenative coupling approach can be carried out on gram-scale (see 3a, Figure ).
