Abstract

"PROCESSOS PARA A PRODUçãO DO COMPOSTO 3,5-DIFLUOROANILINA E DE UM COMPOSTO DE 1-HALO-3,5-DIFLUOROBENZENO" A invenção fornece um processo novo para a produção de um composto de 3,5-difluoroanilina pela reação de 2-halo-4,6-diflúor anilina com um agente de diazotação na presença de um agente redutor para formar um sal de diazónio. A criação de um sal de diazónio potencialmente perigoso é evitada reduzindo-se o sal de diazónio com o agente redutor, para formar um 1-halo-3,5-difluorobenzeno, co-correntemente com a reação de diazotação. O 1-halo- 3,5-difluorobenzeno é então aminado.
