Surface photochemistry: a [1,3] sigmatropic hydrogen shift mediated by CdS
Abstract
Excitation of CdS in the presence of 7,8-diphenylbicyclo[4.2.0]oct-7-ene gave the cation radical of the latter which underwent a reversible [1,3] sigmatropic hydrogen shift; this is the first such observation in a radical cation.
