Abstract

"PROCESSOS DE PREPARAçãO DE UM COMPOSTO, E, COMPOSTOS NITROAROMáTICOS". A invenção tem por objeto novos compostos nitroaromáticos correspondentes à fórmula geral~ 1~ (I'): na qual R, R'1, R~ 2~, Z e n são como definidos na reivindicação 38. Um outro objeto da invenção é um processo de preparação de compostos nitroaromáticos nitrados na posição 4. A invenção visa, igualmente, a utilização destes compostos para a preparação de derivados heterocíclicos do tipo benzofurano ou benzotiofeno nitrados na posição 5. A invenção visa, particularmente, a preparação de 2-alquil-5-nitrobenzeno.
