摘要

Brominaton of 3, 4-dihydrocyclopenta [cd] pyrene (1) with bromine yielded predominantly the corresponding 8-bromide; on the other hand, a similar reaction of cyclopenta [cd] pyren- 3 (4H)-one (2) afforded the 4-bromide. The Friedel–Crafts acetylations of 1 and 2 with acetyl chloride in the presence of aluminum chloride occurred at sites 8, 6, and 1. The isomeric distribution in the acetylation of 1 was similar to that of 2. The relative reactivity of 2 with 1- ...
