(a)

Interpretation Introduction

Interpretation:

The preparation of given product from given organohalide compound and from any other organohalide should be identified.

Concept Introduction:

Preparation of organolithium: They are prepared by reaction of organohalide in presence of two equivalents of Li.

    R-XLi(2eq)R-Li + LiX

Preparation of Grignard reagents: They are prepared by reaction of organohalide in presence Mg in ether solvent.

    R-XEt2OMgR-Mg-X

Reaction between Grignard reagent and water: Grignard reagents are strong bases which in presence of water forms hydrocarbon easily.

Gillman reagent: The lithium copper reagent compound (R2CuLi) are very useful because unlike Grignard reagent and organolithium reagents, they react with organic halides to replace the halide group with an alkyl (R) group.

  • Organocuprate (R2CuLi) are also known as Gilman Reagent.
  • It is prepared from an organolithium compound by reaction with cuprous iodide in diethyl ether or THF as follows.
