The Birch reduction transforms this compound into 1,4-cyclohexadiene, while the Friedel-Crafts reaction can acylate or alkylate this compound. When one of the hydrogens in this compound is replaced with a hydroxyl group, it is known as phenol, while replacing a hydrogen with a methyl group renames it toluene, which has recently replaced this carcinogen in industrial applications. Friedrich Kekulé envisioned the structure
