Propene to 5-methyl-2-pentyne conversion
Synthesis following alkyne, 5-methyl-2-pentyne from propene. You can use only use following compounds.
HBr, Br2/CCl4, Na, concentrated KOH
How to prepare 5-methyl-2-pentyne compounds?
Number of carbon atoms of propene is doubled when 5-methyl-2-pentyne is prepared. So this is extending carbon chain reaction. There is different reactions to extend carbon chain such as
- Through grignard reaction
- Reaction of sodium salt of alkyne and alkyl halide
- aldol condensation
