The use of the oxidant 4-acetylamino-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate in combination with pyridine for the oxidative, dimeric esterification of primary alcohols is described. The ester is the predominant product of the reaction with alcohols containing a β oxygen. In the absence of a β oxygen, the corresponding aldehyde is found in appreciable amounts, but a concentration
描述了氧化剂4-乙酰氨基-2,2,6,6-四甲基哌啶-1-氧代四氟硼酸铵与吡啶的结合用于伯醇的氧化,二聚酯化。该酯是与含有β氧的醇反应的主要产物。在不存在β氧的情况下,发现了相当数量的相应醛,但可以观察到浓集作用。在没有吡啶的情况下,几乎没有酯形成,并且与β-氧化的化合物没有发生明显的反应。δ内酯是由二甘醇和2,2'-硫代二乙醇制备的,未进行硫氧化。
