A practical cyanation of aroyl chlorides with 0.2 equivalent of non-toxic cyanide source, K 4 [Fe(CN) 6 ], 3 mol% AgI, 4 mol% PEG-400, and 3 mol% KI as the catalyst system is described. The reactions were performed in DMF at room temperature and provided the corresponding aroyl cyanides in 64-89% yield, typically in less than ten hours.
描述了使用 0.2 当量无毒氰化物源、K 4 [Fe(CN) 6 ]、3 mol% AgI、4 mol% PEG-400 和 3 mol% KI 作为催化剂体系对芳酰氯进行实际氰化。该反应在室温下在 DMF 中进行,并以 64-89% 的产率提供相应的芳酰基氰化物,通常在不到 10 小时的时间内。
