Synthesis
2-Chloronaphthalene is obtained directly by chlorination of naphthalene, with the formation of more highly substituted derivatives such as dichloro- and trichloronaphthalenes, in addition to the two monochlorinated isomeric compounds: 1-chloronaphthalene and 2-chloronaphthalene.[4]
Properties
2-Chloronaphthalene is a combustible, off-white odorless solid, which is practically insoluble in water. The compound may react with strong oxidizing agents.[5]
Applications
2-Chloronaphthalene can be used for the production of fullerenes.[6]
