Some cyclohexadienols, when heated at 220° with PyHCl, gave, through dehydration and isomerisation, the corresponding benzene derivatives. So 2,6-dibenzyliden-cyclohexanols gave m-dibenzyl-benzenes, 2-benzyliden-1-tetralols gave 2-benzyl-naphthalenes and 2,6-dicyclohexenyl cyclohexanols gave m-dicyclohexyl-benzenes. The correlation between these aromatisations and those of cyclohexenone acetic acids
一些
环己烯醇在与PyHCl加热至220°时,会通过脱
水和异构化反应生成相应的苯衍
生物。所以2,6- dibenzyliden -
环己醇得到米二苄基的苯,2-亚苄基-1- tetralols得到
2-苄基萘和2,6-二
环己烯基
环己醇,得到米二环己基的苯。本文讨论了这些芳香化与
环己烯酮
乙酸与芳酸之间的相关性。还描述了在2-亚苄基-1-四醇的芳构化中获得的一些副产物。
