Anion-catalyzed phase-transfer catalysis was successfully applied to diazotization of pentafluoroaniline in a dichloromethane-aqueous sulfuric acid two-phase system.The resulting diazonium group was coupled in situ with anisole, 1-methoxynaphthalene, and mesitylene, and replaced in situ with bromo, hydryl, and phenyl substituents under a two-phase condition.
