simple and efficient catalyst for the acetylation of alcohols, phenols, and amines. Acetylation reactions with acetic anhydride (1.0 equiv) proceed in excellent yield in the presence of a catalytic amount (0.2 mol%) of PMA at ambient temperature within a relatively short reaction time (<10 min). Structurally diverse alcohols, phenols, and amines undergo acetylation under solvent-free conditions.
已发现磷钼酸 (PMA) 是一种简单而有效的催化剂,可用于醇、酚和胺的乙酰化。在环境温度下,在催化量 (0.2 mol%) 的 PMA 存在下,与乙酸酐 (1.0 equiv) 的乙酰化反应在相对较短的反应时间 (<10 分钟) 内以优异的产率进行。结构多样的醇、酚和胺在无溶剂条件下会发生乙酰化。
