1,2-DERIVATIVES OF ACENAPHTHYLENE. IX. NEW DATA ON ADDITION OF HALOGENS TO ACENAPHTHYLENE

Acenaphthylene adds molecular halogens nonstereospecifically.The relative amount of the Z-dihalide increases with decrease in the polarity of the solvent.Z-1,2-dibromo-1,2-dihydroacenaphthylene is not changed after a year at 4-6 deg C; the best solvent for its production is hexane.

Concerted and Stepwise Mechanisms in the Eliminations from 1,2-Dihalogenoacenaphthenes Promoted by Potassium tert-Butoxide and Potassium Ethoxide in the Corresponding Alcohols

Anti and syn eliminations from cis- and trans-dihalogenoacenaphthenes, respectively, have been investigated in t-BuOK-t-BuOH and EtOK-EtOH.The leaving group ability order for the syn eliminations in t-BuOK-t-BuOH is F > Cl ca.Br, which suggests an (E1cB)I mechanism.Also consistent with this mechanism is the observation that from trans-1-chloro-2-fluoroacenaphthene only HF is eliminated.In EtOK-EtOH the order of leaving group ability for the syn eliminations is Br > Cl > F, which might suggest an E2 mechanism; however, the leaving group effects are very small, anda stepwise mechanism cannot be excluded.The anti eliminations from the cis-dihalogenoacenaphthenes exhibit a substantial leaving group effect; on this basis and also on considering the β-halogen effect on the rate of elimination, a concerted mechanism is suggested.

Irreversible E1cb Mechanism in the syn Eliminations from 1,2-Dihalogenoacenaphthenes Promoted by Potassium t-Butoxide in t-Butyl Alcohol

The lack of a significant leaving group effect and the preferential departure of the "poorer" leaving group suggest an irreversible E1cb mechanism for the title reactions.
