Acenaphthene-5-sulfonic acid

In particular 4,4 -diacenaphthyl oxide was prepared by fusing 4-chloro-acenaphthene and acenaphthene-4-sulfonic acid with an alkali [86, 87] or from 4-oxyacenaphthene according to the foUowing scheme [88, 89] ... 

The sequence 112— 113 provides a synthetic route to obtain derivatives of acenaphthene-4-sulfonic acid which cannot be prepared by direct sulfonation of the hydrocarbon. ...

Acenaphthene. Acenaphthene 44 is structurally related to the alkyl-naphthalenes and consequently the preferred orientation of sulfonation should be in the 3- and 5-positions. However, the literature is confusing with concentrated sulfuric acid at 100 °C, the product was first considered to be the 5-sulfonic acid, but later it was argued that this assignment was erroneous and that the product was the 3-isomer. ... 

Acenaphthene. (CAS 83-32-9]. Acenaphthene is a hydrocarbon, C12H10, present in high temperature coal tar. Acenaphthene may be halogenated. sulfonated. and nitrated in a manner similar to naphthalene. Oxidation first yields acenaphthenequmone, followed by 1.8-naphthalenedicarboxyhc acid anhydride and pesticides. 

This bisfnaphthalic anhydride) was prepared from acenaphthene derivative-4,4 -diacenaphthyl sulfone, which was synthesized by the interaction of acenaphthene with a mixture of dimethybulfate and sulfuric anhydride [94] or chlorosulfonic acid [95]. Sulfone-bis-(4,5-dicarboxynaphthyl l) dianhydride results from oxidation of bis-acenaphthyl with potassium permanganate in pyridine [94] ... 

Its isomer 2,2 -sulfone-bi naphthalic anhydride) resulted from sulfonation of acenaphthene with chlorosulfonic acid at 125-130 °C and subsequent oxidation of the obtained bis-(acenaphthyl)-sulfone with chromium anhydride [95] ...
