3-Anilino-1-propanol derivatives 4a–c, 5a–c, 6a–c containing primary, secondary, and tertiary alcohols and PhNH, PhNMe, and (Ph)2N were prepared and subjected to gas-phase pyrolysis in a static reaction system. The pyrolytic reactions were homogeneous and followed a first-order rate equation. Reactions took place by retro-ene process, with the exception of compounds 5a and 5b. Analysis of the pyrolysate
制备包含伯,仲和叔醇以及PhNH,PhNMe和(Ph)2 N的3-苯胺-1-丙醇衍生物4a – c,5a – c,6a – c,并在静态下进行气相热解反应系统。热解反应是均相的,并且遵循一阶速率方程。除化合物5a和5b外,反应通过逆烯法进行。对热解产物的分析表明产物为N取代的苯胺和羰基化合物。根据消除途径的合理过渡态,对九种被研究的3-氨基醇中每一种的动力学结果和产物分析进行了合理化处理。
