Abstract
A one-pot diazotization fluoro-dediazoniation procedure of anilines was successfully accomplished to produce fluoroarenes in highyields by using organic base-HF agents freeofvolatile HF a t the dediazoniation step. Moreover, a mixture of such an agent with chlorobenzene, forming a liquid - liquid two-phase system, was found t o be a highly advantageous and suitable system for repeated use of adiazotization fluoro-dediazoniation agent.Keywords
