Novel photorearrangement of 2,5-dihydroxytriptycene and ionic rearrangement of the photoproduct
Abstract
Irradiation of 2,5-dihydroxytriptycene in methanol with Pyrex-filtered u.v. light gave an epoxyketone which rearranged back to a triptycene-like ketone by reduction with LiAlH4 followed by dehydration over P2O5.
