Rearrangements of Polyines. IV. Tetraphenyl-di-(3-methyl-3-ethylpentinyl-1)-ethane

Abstract

Vol. 55 hydrate upon phenylbromofluorene. With sodium in liquid ammonia solution, the hydrazo compound reacted to form a product, which, when hydrolyzed, yielded phenylfluorene. With various oxidizing agents, hydrazophenylfluorene yielded mainly phenylfluoryl peroxide.3. In experiments with palladium black, evidence was obtained for the possible momentary existence of azophenylfluorene; the compound, if formed, decomposed under the experimental conditions yielding nitrogen, phenylfluorene and dibiphenylenediphenylethane. The action of oxygen upon hydrazophenylfluorene in the presence of palladium black led to the formation of phenylfluoryl peroxide and phenylfluorenol.4. The action of hydrogen upon dibiphenylenediphenylethane and upon phenylfluoryl peroxide in the presence of palladium black yielded phenylfluorene.Washington, D. C.

Isomerization of Hydrocarbons.

“…The work of Marvel and coworkers on the acetylenic ethanes (16,41,43,108,116,120) has shown that these rearrange readily into isomeric compounds without catalysts. Although the structure of these rearranged isomeric compounds has not been proven definitely, evidence supports the diolefin structure.…”
