摘要

Results The eliminations from 1 and 2 have been investigated in t-BuOK-t-BuOH and EtOK- EtOH. From la, c, e and 2a, c, where X= Y, the expected 1-halogenoacenaphthylene has been obtained as the sole reaction product. The product distribution from the dihalogenoacenaphthenes lb, d and 2b, where X# Y, is reported in Table I. An interesting observation is that in both the basesolvent systems investigated, HF is eliminated in prefer-
