please show all work done to solve the problem, if you could write it down and upload a picture that would be best, thank you

Give formula (not structure) of the following and classify each as either a Grignard reagent, an organolithium compound or Gilman's reagent: Butyllithium Lithium diethylcopper vinyl magnesium bromide propyl magnesium bromide Lithium dipropylcopper Starting from Propyl bromide, give equations and reagents/conditions to show how you would prepare i) a Grignard reagent, ii) An organolithium compound and iii) an organocuprate

Explanation / Answer

1) butyl lithium-------------CH3-CH2-CH2-CH2-Li-----------------------organo lithium

2)lithium diethyl copper--(-CH3-CH2)2 CuLi----------------------------gilmans reagent

3)vinyl magnesium bromide----CH2=CH-Br----------------------grignard reagent

4) propyl magnesium bromide--------CH3-CH2-CH2-Br----------grignard reagent

5)lithium dipropyl copper------------------(CH3-CH2-CH2)2 CuLi------gilmans reagent

7)

a) CH3-CH2-CH2-Br + Mg + dry ether--------------------------.> CH3-CH2-CH2-MgBr

b)CH3-CH2-CH2-Br + 2 Li-------------------> CH3-CH2-CH2-^- Li^+ + LiBr

   C)

CH3-CH2-CH2-Br + 2 Li-------------------> CH3-CH2-CH2-^- Li^+ + LiBr

CH3-CH2-CH2-^- Li^ + Cu +THF(-78^0 C)------------------.>CH3-CH2-CH2 Cu
