Organohalides are treated with lithium metal to yield an organolithium, which is in turn treated with copper (I) iodide to yield the corresponding Gilman reagent. Decide what lithium diorganocopper (Gilman) reagent is needed to prepare 1-butylcyclohexene from 1-iodocyclohexene.

Explanation

To convert corresponding halides to final product we have to use Gilman reagents. Gilman reagents are prepared in the laboratory with carbohydrates which will be substituents for starting material.

The introduced group needs to be an akyl group with eight carbon atoms that is octyl.
