Alkanes are rarely prepared from other types of compounds because of economic reasons. However, ignoring financial considerations, alkanes can be prepared from the following compounds:
1. Unsaturated compounds via catalytic reduction ![]()
2. Alkyl halides via coupling (Wurtz reaction) ![]()
3. Alkyl halides via Grignard reagent ![]()
4. Alkyl halides via reduction ![]()
Although organic chemists refer to the above diagrams as “equations,” they are not balanced. In addition, not every product formed is shown. These diagrams are really reaction schemes.
