Web15 nov. 2024 · Wurtz reaction is not very efficient and hard to initiate. If you use a mixture of alkyl halides you will obtain a difficult to purify mixture of products including homo-coupling from both starting materials and reduction products, so the obvious way to approach this is to use a single starting material.
