8-diazabicyclo[5.4.0]undec-7-en-8-ium acetate was employed for the acetylation of various phenols, alcohols, and amines in good-to-excellent yields at 50 °C under solvent-free conditions in a short time. Compared with existing methods based on conventional catalysts and toxic solvents, the reported method is simple, mild and environmentally viable. Furthermore, the ionic liquid was conveniently separated
摘要Lewis碱性离子液体1,8-二氮杂双环[5.4.0] undec-7-en-8-乙酸乙酸盐在50°C和50°C的条件下以良好的优异产率用于各种酚,醇和胺的乙酰化在短时间内无溶剂的条件下。与基于常规催化剂和有毒溶剂的现有方法相比,所报道的方法简单,温和且在环境上可行。此外,将离子液体方便地与产物分离并易于再循环以优异的产率催化其他乙酰化反应。 图形概要 。
