4-Chloroanisole is an electron-rich chloroarene. It undergoes Ullmann-type homocoupling catalyzed by in situ generated Pd colloids.[1] Reaction of 4-chloroanisole with Cu(II)-smectite in n-hexane, carbon tetrachloride or dichloromethane has been studied.[2] The nucleophilic photosubstitution reactions, photocyanation and photohydrolysis of 4-chloroanisole has been studied by time resolved spectroscopy.
