Abstract

<B>"PROCESSOS PARA A PREPARAçãO DE UM COMPOSTO E PARA A FORMAçãO DIRETA DE UM CLORETO DE ACILA"<D>. Uma reação de substituição nucleofílica em dialobenzenos opcionalmente substituídos é executada na presença de um catalisador opcional, seguida pela formação de, e subsequente carboxilação, de um intermediário de reação de Grignard. Em particular, a presente invenção proporciona um processo que conduz a ácidos alcoxibenzóicos, formiloxibenzóicos, alcanoiloxibenzóicos e hidroxibenzóicos opcionalmente substituídos a partir de 2,6-dialobenzenos 1- substituídos. A invenção também fornece um processo para a formação direta de um cloreto de acila a partir de um reagente de Grignard por resfriamento rápido com fosgênio.
