Four-Step Synthesis Pathway
The synthesis of epoxide from benzene typically involves a four-step pathway:
- Bromination of benzene to form bromobenzene
- Reaction of bromobenzene with sodium hydroxide to form phenol
- Reaction of phenol with epichlorohydrin to form 2-chloromethyl-2-phenyl-1,3-propanediol
- Treatment of 2-chloromethyl-2-phenyl-1,3-propanediol with sodium hydroxide to form the epoxide
