Can Gilman reagents react with ketones?
Gilman reaction is a name reaction as typified by 1,4-additions of ?,?-unsaturated ketones as well as S_N2-type alkylation of alkyl halides. Gilman reagents are organocopper compounds typically illustrated by C-Cu-C core with a lithium counterion and are particularly useful for the Gilman reaction.
What reagents are used in ketones?
The two most commonly used compounds of this kind are alkyl lithium reagents and Grignard reagents.
What do Grignard reagents with ketones give?
Reacting a Grignard reagent with a ketone gives a tertiary alcohol.
A Gilman reagent is a lithium and copper (diorganocopper) reagent compound, R₂CuLi, where R is an alkyl or aryl.
