Abstract
Photochemically-induced hydrogen shifts in 7-(p-chlorophenyl), 7-phenyl, 7-(p- methoxyphenyl) and 7-p-tolylcycloheptatrienes (Ia—d) were studied. The possibility of hydrogen 1, 7 and 1, 3 shifts in these compounds was examined on both experimental and theoretical grounds. It was concluded that the hydrogen 1, 7 shift is the only suprafacial hydrogen shift possible in the excited cycloheptatriene system. In this study all the isomers ...
