摘要

通过共催化选择性 C-C 键裂解，然后对烯烃底物进行硅烷过氧化反应，生成了一系列烷基硅基过氧化物，而且产量和选择性都很好。通过过渡金属催化裂解生成的烷基硅基过氧化物并随后与偶联剂官能化，可进一步转化生成一系列二羰基化合物。这种两步转化以一锅方式进行，提高了这种方法的实用性。为了解释烯烃底物的 C-C 键裂解和随后的硅基过氧化反应，提出了一种合理的反应机理。

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.
