摘要：
The reaction of 4,7-dibromo[1,2,5]thiadiazolo[3,4-d]pyridazine with alcohols and sodium alkoxides was evaluated under various conditions. Depending on the reaction conditions, either alkoxy or hydroxy derivatives of [1,2,5]thiadiazolo[3,4-d]pyridazine can be obtained. 4,7-Di-(dodecyloxy)- and 4,7-di(hexyloxy)[1,2,5]thiadiazolo[3,4-d]pyridazines, which may be of interest as the compounds exhibiting liquid crystalline properties, were synthesized for the first time.
