simple and efficient catalyst for acylation of alcohols, phenols and thiols. It is also very effective for geminal diacylation of aldehydes. The acylation reaction using acetic anhydride proceeds in excellent yield in the presence of catalytic amounts ofthallium(III) chloride (1 mol%) at room temperature within relatively short reaction times (<20 min). Structurally diverse alcohols, phenols, thiols and
:氯化铊(III)是一种简单有效的醇、酚和硫醇酰化催化剂。它对醛的偕二酰化也非常有效。在室温下,在催化量的氯化铊 (III) (1 mol%) 存在下,使用乙酸酐的酰化反应在相对较短的反应时间 (<20 分钟) 内以优异的产率进行。结构多样的醇、酚、硫醇和醛在无溶剂条件下进行酰化。
