Abstract

The title compound (2) was prepared through the photochemical transformation of several triptycene derivatives. Electrophilic substitution reactions of 2 took place primarily at the 6- position: the Vilsmeier reaction gave the 6-formyl derivative in good yield; bromination afforded the 6-bromo derivative, accompanied by a small amount of the 6, ll-dibromo compound; nitration yielded mainly the 6-nitro compound, with the 8-nitro derivative as a ...
