Abstract: | In an attempt to prepare short-bridged hydroxymetacyclophanes , the spirocyclohexadienones were pyrolyzed by flash vacuum thermolysis (FVT). Instead of , variable amounts of 4-(5-hexenyl)phenol (), β-hydroxybenzocycloalkenes () and 4-(trans-1-alkenyl) phenols () were obtained. The formation of these products is explained by invoking cleavage of a spiro bond in under formation of the intermediate diradical which, depending on the length of the aliphatic chain and on the temperature, has several pathways open for isomerization to spin-paired products. |
