3,5-Dinitrobenzoyl chloride → HCID 86735498, compound

Participants

Reaction Steps

Copoly(N-vinyl carbazole-Vinyl alcohol) (II) (2.0 g) was dissolved in 50 ml of anhydrous pyridine. 3,5-Dinitrobenzoyl chloride (3.88 g) in 15 ml of anhydrous benzene was added with stirring to the pyridine solution. The resulting orange solution was stirred at room temperature for 4 hours. The small amount of solid remaining in the reaction mixture was collected on a filter and the filtrate was poured into 400 ml of methanol. The isolated polymer was purified by two precipitations from tetrahydrofuran into methanol to give 3.2 grams of a yellow powder. Nitrogen analysis demonstrated that the reaction of the alcohol groups with the acid chloride was nearly quantitative.
