Abstract
Patente de Invenção: <B>"PROCESSO PARA A PREPARAçãO DE CLORO-BENZOXAZóIS"<D>. A invenção refere-se a um processo para a preparação de cloro-benzoxazóis da fórmula (I), na qual R¹, R² e R^ 4^ são tal como definidos na reivindicação 1, e (Caso a) R³ = H, halogênio, CN, NO~ 2~, C~ 1~-C~ 5~-alquila, C~ 1~-C~ 5~-alcóxi, arila ou arilóxi, sendo que cada um dos 4 radicais mencionados por último não está substituído ou está substituído, ou (Caso b) R³ = cloro, caracterizado pelo fato de que benzoxazóis da fórmula (II), na qual R¹, R² e R^ 4^ têm o mesmo significado tal como na fórmula (I) e R³, no caso (a), é tal como definido na fórmula (I), e R³, no caso (b), é hidrogênio, são reagidos em presença de um catalisador ácido, com um agente de cloração, para formar o produto de monocloração (I) ou, no caso (b), com um excesso do agente de cloração, para formar o produto de dicloração (I), no qual R³ = cloro.
