Selective mono-fluorination of 1,2- and 1,3-diols was achieved using N,N-diethyl-4-methoxybenzamide diethyl acetal and Et3N-3HF. The reaction proceeds through a cyclic acetal of the benzamide, and only one hydroxy group was fluorinated and another one was acylated.
使用N,N - N-二乙基-4-甲氧基苯甲酰胺二乙基乙缩醛和Et 3 N-3HF实现1,2-和1,3-二醇的选择性单氟化。反应通过苯甲酰胺的环状缩醛进行,仅一个羟基被氟化,另一羟基被酰化。
