Caught in the act: 1HNMR spectroscopy was used to monitor the loss of reactant and formation of product during the induction and burst phases of Soai'sautocatalysis reaction. A transientintermediate was observed at 0 °C and identified as an alkoxyacetal formed from one aldehyde and two alkoxide moieties (see picture).
参与其中:1 H NMR光谱用于监测Soai自催化反应的诱导阶段和猝发阶段期间反应物的损失和产物的形成。在0°C时观察到一个过渡中间体,并鉴定为由一个醛和两个醇盐部分形成的烷氧基缩醛(参见图片)。
