WebJul 10, 2013 · Now we would need to convert benzene into toluene. And so we could do that using a Friedel-Crafts alkylation reaction. And so we need one carbon. So for our alkyl chloride, we would need a one-carbon alkyl chloride, so CH3 Cl. And our catalyst for Friedel-Crafts alkylation would be aluminum chloride, like that. So our synthesis is complete. WebThe synthesis of phenol by one-pot oxidation of benzene with dioxygen (O 2) is a significant conceptual and practical challenge because benzene has low reactivity to O 2 at room temperature and ambient pressure. Furthermore, phenol is more reactive than benzene and is easily overoxidized, so complete oxidation is more likely to proceed in the benzene …
