its all about organometallic chemistry of zinc and copper metal
Reaction of Organocuprates O-Trapping. • enolate generated from enone below reacts at O with chlorotrimethylsilane in the presence of triethylamine to produce the trimethylsilyl enol ether. • Silyl enol ethers are valuable intermediates for the preparation of regiodefined enolates.
Reaction of Organocuprates O-Trapping • Treatment of enolates with (RO) 2 P(O)Cl also results in O- trapping to yield the corresponding enol phosphates. • Dissolving metal reduction of enol phosphates is useful for the deoxygenation of ketones with concomitant, regiospecific formation of the alkene.
