Carbon-Chain Elongation by Co-Catalyzed Selective C–C Bond Cleavage and Subsequent Silylperoxylation of Alkene Substrates

A Co-catalyzed selective C–C bond cleavage followed by the silylperoxylation of alkene substrates generated a series of alkylsilyl peroxides with good yields and selectivities. Further transformation through transition-metal-catalyzed cleavage of the resulting alkylsilyl peroxides and subsequent functionalization with coupling partners could generate a series of dicarbonyl compounds. This two-step transformation was carried out in a one-pot manner, which enhances the practicability of this approach. A plausible reaction mechanism was proposed to interpret the C–C bond cleavage and subsequent silylperoxylation of the alkene substrates.
