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.

Synthesis of New Functional Acenaphthylene Derivatives. 2. Regioselective Electrophilic Substitution of Silylated Acenaphthenes and Acenaphthylenes

New silylated derivatives have been synthesized in the acenaphthylene series by appropriate silylation reactions, followed by oxidation in the case of 3a. 1a and 3a as well as 1-(trimethylsilyl)-and 1,2-and 1,5-bis(trimethylsilyl)acenaphthylenes (2a, 4a, and 5a, respectively) have been used as regioselective precursors of 5-functional acenaphthenes and 1-monofunctional and 1,2-and 1,5-bifunctional acenaphthylenes by electrophilic substitution of the trimethylsilyl group(s).Mono- and bisulfonations succeeded in all cases as well as the acylation or iodination of monosilyl derivatives and 1,2-diodination of 4a.Thus, various novel functional acenaphthenes and acenaphthylenes could be prepared by a convenient route.In contrast, attempts at diodination of 5a and diacylation of 4a and 5a were unsuccessful.

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.
