Answer:
The Corey–House synthesis (also called the Corey–Posner–Whitesides–House reaction and other permutations) is an organic reaction that involves the reaction of a lithium diorganylcuprate (R2CuLi) with an organyl (pseudo)halide (R'X) to form a new alkane, as well as an ill-defined organocopper species and lithium halide ...
The Corey–House synthesis (also called the Corey–Posner–Whitesides–House reaction and other permutations) is an organic reaction that involves the reaction of a lithium diorganylcuprate (R2CuLi) with an organyl (pseudo)halide (R'X) to form a new alkane, as well as an ill-defined organocopper species and lithium halide as byproducts.
Li+[R–Cu–R]– + R'–X → R–R' + "RCu" + Li+X–
In principle, a carbanion equivalent such as an organolithium or Grignard reagent can react directly (without copper) with an alkyl halide in a nucleophilic substitution reaction to form a new carbon–carbon bond. However, aside from the use of metal acetylides as nucleophiles, such a process rarely works well in practice due to metal–halogen exchange and/or the formation of large amounts of reduction or elimination side-products.As a solution to this problem, the Corey–House reaction constitutes a general and high yielding method for the joining of two alkyl groups or an alkyl group and an aryl group.
