Preparação de N-alquil derivados do 1-bromo-2,4-dinitrobenzeno e do 1-cloro-2-nitrobenzeno: Uma alternativa às aulas práticas de substituição nucleofílica aromática Preparation of N-alkyl derivatives of 1-bromo-2,4-dinitrobenzene and 1-chloro-2-nitrobenzene: An alternative to nucleophilic aromatic substitution practices

Autor: Ayres Guimarães Dias, Felipe Martins Alves Pereira, Renato de Oliveira Soares

Publikováno v: Química Nova, Vol 31, Iss 7, Pp 1885-1887 (2008)

Preparation of the title compounds are described as an alternative nucleophilic aromatic substitution for practices in the graduate laboratory. The low toxicity and disponibility of the reagents make a suitable procedure approach to experiments regar
