摘要

A number of polycyclic aromatic thiones have been prepared from the corresponding ketones. Several of the thiones in which there is a free peri position cyclize, on excitation in the π*← n band, to give thiophene derivatives. The structures of these were proven by application of physical methods and by desulfurization to the corresponding benzyl derivatives. The formal hydrogen 1, 3 migration involved was, in one case, shown to be ...
