Alkenylation of aldehydes with β-silyl ketones proceeded to afford β,γ-unsaturated ketones with skeletal rearrangement. The reaction mechanism involved tandem aldol/[1,4]-Brook/1,2-addition/ring cleavage of cyclopropane. [1,4] Brook rearrangement took place with complete inversion of configuration at the carbon center.

Organocuprates and chlorotrimethylsilane are compatible as separate species in THF or ether solution at −50 to −78°, and in combination can both accelerate and improve 1,4-addition reactions with conjugatedcarbonylcompounds.
