Abstract

"MéTODO PARA PREPARAR 2,3-DICLOROPIRIDINA 1." Um método para preparar 2,3-dicloropiridina é revelado, em que 3-amino-2-cloropiridina seja posto em contato com um nitrito de álcali metal na presença de ácido clorídrico aquoso para formar um sal de diazónio; e o sal de diazónio seja subseqüentemente decomposto na presença de catalisador de cobre em que no mínimo cerca de 50% do cobre seja o estado de oxidação do cobre (II).
