Despite intensive study of the pyrolysis of C/sub 7/H/sub 8/ compounds, the methylenecyclohexadienes, o- and p-isotoluenes, 1 and 2, respectively, have received little attention. Both 1 and 2 are ca. 23 kcal/mol less stable than toluene, and so their pathways for isomerization are of concern. While both 1 and 2 have been prepared, their sensitivity to acid and base have precluded or obscured efforts
尽管对 C/sub 7/H/sub 8/ 化合物的热解进行了深入研究,但对亚甲基环己二烯、邻和对异甲苯 1 和 2 的关注却很少。1 和 2 都是大约。23 kcal/mol 的稳定性不如甲苯,因此它们的异构化途径值得关注。虽然 1 和 2 都已制备,但它们对酸和碱的敏感性已经排除或模糊了观察它们的热行为的努力。作者报告了这些材料的苯溶液二级热解反应,为研究它们的稀气相异构化做准备。
