Gas phase thermal isomerizations of twelve acetylenic systems, all of which can in principle undergo two successive pericyclic steps, are described. The substrates, the syntheses and spectroscopic properties of which are presented, are formal derivatives of but-2-yne, with different functional groups in the 1- and the 4-positions. The Cope, Claisen, Claisen ester, retro-ene, 1,5-hydrogen shift, and
描述了十二个炔属体系的气相热异构化,所有这些体系原则上都可以经历两个连续的周环步骤。底物,其合成和光谱特性,是but-2-yne的形式衍生物,在1-和4-位具有不同的官能团。Cope、Claisen、Claisen 酯、逆烯、1,5-氢转移和 1,5-均氢转移过程被用作构成串联过程的周环步骤。获得的热解产物的组成是在很宽的温度范围内确定的,并讨论了产生热解产物的各个步骤的机制。
