secondary, and tertiary alcohols, and phenol, into the corresponding esters at room temperature. The method uses a titanium(III) species generated from a substoichiometric amount of titanocene dichloride together with manganese(0) as a reductant, as well as methylene diiodide. It involves a transesterification from an ethyl ester, or a reaction with an acyl chloride. A radical mechanism is proposed
已开发出一种在室温下将伯醇、仲醇和叔醇以及苯酚转化为相应酯的方法。该方法使用由亚化学计量二氯化钛和作为还原剂的锰 (0) 以及二碘甲烷生成的钛 (III) 物质。它涉及乙基酯的酯交换,或与酰氯的反应。为这些转换提出了一种激进的机制。
