With a view to synthesize a simple functional derivative of pentalene (Ⅰ) so as to testify Hückel's theory of aromaticity, the compound bicycle (3.3.0) octa-3, 7-dien-2, 6-dione (Ⅲ), (the enol form of which is 1, 4-dihydroxypentalene(Ⅱ)), was obtained.The key intermediate, bicyclo (3.3.0) octan-2, 6-dione (Ⅳ), was prepared through a new route with an overall yield of 19—36%: Hydrogen chloride was added to cyclopentadiene to form 3-chlorocyclopentene(b.p. 27—28°/11—12,n_p~(250) 1.4748; 85—92%), which was coupled...

With a view to synthesize a simple functional derivative of pentalene (Ⅰ) so as to testify Hückel's theory of aromaticity, the compound bicycle (3.3.0) octa-3, 7-dien-2, 6-dione (Ⅲ), (the enol form of which is 1, 4-dihydroxypentalene(Ⅱ)), was obtained.The key intermediate, bicyclo (3.3.0) octan-2, 6-dione (Ⅳ), was prepared through a new route with an overall yield of 19—36%: Hydrogen chloride was added to cyclopentadiene to form 3-chlorocyclopentene(b.p. 27—28°/11—12,n_p~(250) 1.4748; 85—92%), which was coupled by magnesium to 1,1'-bi-2-cyclopentenyl (V, b.p. 70°/18, n_p~(230) 1.4880; 80—92%). This diene (Ⅴ) was ozonized and the ozonide was decomposed with 40% peracetic acid to yield hexane-1, 3, 4,6-tetracar-boxylic acid (Ⅵ). The tetramethyl derivative (Ⅶ) of the acid (low melting crystals of a cis-trans mixture, b.p. 144—1.47°/0.07 mm; 66—75% overall yield from (Ⅴ)) was dicyclized by potassium t-butoxide to 3, 7-dicarbomethoxy-bicylo (8.8.0) octan-2,6-dione (Ⅷ, m.p. 90.4—92.4°, cis-trans mixture; 52—67% yield). Upon decarbomethoxylation, the latter (Ⅷ) yielded the dione (Ⅳ) (m. p. 45—45.5°; 79—84% yield) which was found to be identical with Ruzicka's product. Lithium aluminmn hydride reduction of the dione (Ⅳ) gave the corresponding diol (Ⅸ) (b. p. 106—106.5°/0.005, 65%), but the diol failed to form pure dienes in fair yield by Chugaev dehydration.The dione (Ⅳ) was chlorinated in acetic acid to dichlorobicyclooctandione (X, 64—74%), which was transformed into its corresponding diethyleneketal (Ⅺ) (separated into 3 forms: α-, m. p. >210° d.; β-, m. p. 126—127°; γ-, m. p. 100—101°; β- and γ- forms shown to be the 3, 7-dichloro derivatives. 52—65% yield). Potassium t-but-oxide dehydrochlorinated the dichloroketal (Ⅺ) to bicylo (8.8.0) octa-3, 7-dien-2, 6- dione diethyleneketal (Ⅻ, m. p. 99—100.5°; 69% yield), upon ketal-exchange of (Ⅻ) with excess acetone, the synthesis of the diendione (Ⅲ) (m. p. 75.5—76.5°, 76% yield) was accomplished. The structure of all the above mentioned compounds was established by analyses, chemical transformations and spectral data.The diendione (Ⅲ) does not contain any detectable amoumt of its enol form, 1, 4-dihydroxypentalene (Ⅱ), neithor can it be forced to form stable enolized forms. Thus it is believed that the pentalene system does not pessess aromatic character.

本文报告烯酮(Ⅲ)的合成,与(Ⅲ)相当的烯醇体即1,2-二羟二环辛四烯(Ⅱ)。合成的关键中間物,二酮(Ⅳ),由一新合成步驟制备,总产率19—36%:低温加氯化氫于环戊二烯得3-氯环戊烯(85—92%),再用鎂使之双合而成二烯(Ⅴ)(80—92%)。(Ⅴ)的臭氧化合物經过氧乙酸分解而形成四元酸(Ⅵ),酯化后得其四甲酯(Ⅶ)(由(Ⅴ)至(Ⅶ)总产率66—75%);后者可环化为二甲氧羰基二酮(Ⅷ)(52—67%),(Ⅷ)經水解脫羧即生成二酮(Ⅳ)(79—84%)。二酮(Ⅳ)可还元为二醇(Ⅸ)(65%)。由二酮(Ⅳ)再經四步反应后即得烯酮(Ⅲ):氯化二酮(Ⅳ)得二氯二酮(Ⅹ)(64—74%);將(Ⅹ)与乙二醇一同脫水縮合得縮二酮(Ⅺ)(52—66%);自(Ⅺ)脫氯化氫后得二烯縮二酮(Ⅻ)(69%),后者与丙酮經交換反应即变为烯酮(Ⅲ)(76%)。上述各化合物的分子結構,均經証明。烯酮(Ⅲ)不含其相当的烯醇体(Ⅱ);在鹼性溶液中亦不能形成稳定的二环幸四烯二醇-陰离子。因此可以相信,二环辛四烯体系具有芳族性的可能性極微。

The shaking batch tests in triangular flasks with powdered activated carbon showed that the adsorption of eight kinds of aromatic compounds had reached equilibrium in five minutes. The activated carbon adsorption rate was found to be governed by the microporous diffusion. It was found that the ozonation had improved the activated carbon adsorption capacities and performance for the tannin and m-dinitrobenzene, while exhibited adverse effects on adsorption of four kinds of aromatic compounds. Moreover, the ozonation products of five kinds of aromatic compounds estimated in terms of COD_(Mn) as well as the formaldehyde were difficult to be adsorped by activated carbon due to stronger polarity they exhibit. The resistance of eight kinds of aromatic compounds to activated carbon adsorption were compared, and the related mechanisms were explained from the viewpoint of polarization effects of different substitute groups on the benzene rings.

本文引用弗伦德里希吸附等温式评价了臭氧化对活性炭吸附水中某些有机化合物的影响。在三角烧瓶中用粉末活性炭做的间歇式振荡试验表明,八种芳族化合物均能在5分钟内达到吸附平衡。发现微孔扩散是控制活性炭吸附速度的决定因素。试验发现,在适宜的投量下,臭氧化可改善活性炭对丹宁和间二硝基苯的吸附性能,但是对其它四种硝基芳烃的吸附有不利影响。还发现有五种硝基芳烃的臭氧化合物(以CODM_(Mn)计量)和甲醛,因极性较强而不易被活性炭吸附。本文对比了八种芳族化合物被活性炭吸附的难易,并以苯环上不同取代基的极化效应的观点解释了有关的机理。
