amount of ruthenium(III) acetylacetonate (2 mol%) [Ru(acac)3] enables solvent-free acetylation of phenols, alcohols, and amines at ambient temperature in good to excellent yields. Furthermore, the catalyst could be recovered and reused at least three times without a significant loss in yields.Key words: acetylation, protecting groups, ruthenium(III) acetylacetonate, phenols, alcohols, amines.
催化量的乙酰丙酮钌 (III) (2 mol%) [Ru(acac)3] 能够在环境温度下对酚、醇和胺进行无溶剂乙酰化,收率非常好。此外,催化剂可以回收和重复使用至少3次,收率没有显着损失。关键词:乙酰化,保护基团,乙酰丙酮钌(III),酚类,醇类,胺类。
