Alkyl halides react with dialkyl copper reagents to give
  1. (A)alkenes
  2. (B)alkyl copper halides
  3. (C)alkanes✓ Correct
  4. (D)alkenyl halides

Answer: (C)

Solution

Dialkylcopper reagents, the Gilman reagents , are made precisely to forge carbon-carbon bonds. When one meets an alkyl halide the two organic groups couple together, , joining the carbon skeletons into a single larger chain. The product of this Corey-House coupling is an alkane.
