摘要

Excitation of CdS in the absence of oxygen in the presence of cyclic derivatives of diphenylcyclobutene gave the cation radical of the latter which underwent a reversible double bond migration. The structures of the products were established on the basis of spectral data (1H, 13C NMR, MS, UV). Tests were performed to show that the reaction proceeds, at least in part, intramolecularly, and, therefore, represents the first example of a ...
