2-dihydronaphthalene derivatives (where X is H, MeO); FVP of 1-aryl-3-benzyloxy1-1-butenes and benzyl cinnamyl ethers [ArCH=CHCH(X)OCH2Ph, where Ar is phenyl, p-MeO, p-Me, p-Cl, X is H, Me, Ph] gave the corresponding but-2-en-1-ylbenzene derivatives (ArCH2CH=CH-X, where X is H, Me, Ph) together with benzaldehyde. The proposed mechanism of these pyrolytic transformations was supported by kinetic and product
4-芳基-3-丁烯-2-醇的快速真空热解 (FVP) [ArCH=CH-CH(CH3)OH,其中 Ar 是苯基、p-MeO、p-Me、p-Cl、p-NO2]得到相应的丁-1,3-二烯-1-基苯(ArCH=CH-CH=CH2,其中Ar是Ph、p-MeO、p-Me、p-Cl、p-NO2)和7-X-1 ,2-二氢萘衍生物(其中 X 为 H,MeO);1-芳基-3-苄氧基1-1-丁烯和苄基肉桂基醚的FVP [ArCH=CHCH(X)OCH2Ph,其中Ar是苯基、p-MeO、p-Me、p-Cl,X是H、Me、Ph ]与苯甲醛一起得到相应的丁-2-烯-1-基苯衍生物(ArCH2CH=CH-X,其中X是H、Me、Ph)。这些热解转化的拟议机制得到了动力学和产品分析的支持。
