The same cyclization also succeeds in the absence of a carboxylic group. Heating the fulvene (361), prepared by condensation of o-chlorobenzaldehyde with fluorene, with potassium hydroxide in boiling quinoline leads to benzo(e)acephenanthrylene (J62)127> ... [Pg.225]

The oxidative cyclization of 4-(2-styryl)- (150, R = Ph) and 4-(2-naphthyl-vinyl)- (150, R = naphthyl) benzo[a]quinolizinium salts affords 6a-azoniapicene (151) and 6a-azoniabenzo[6]picene (152) salts, respectively. Interestingly the corresponding pyridyl compound (150, Ar = 2-pyridyl) undergoes a five-mem-bered ring cyclization, giving a 3b-azonia-5-(2-pyridyl)acephenanthrylene salt (153). No explanation is provided. Finally, the ET sensitized 1-aza-di-jt-methane... [Pg.160]

Being interested here in the volatile components of coffee aroma, we shall arbitrarily limit the list of the aromatic hydrocarbons to tricyclic structures. The higher fused polycyclic hydrocarbons (fluoranthene [206-44-0], pyrene [129-00-0], chrysene [218-01-9], benz[ ]anthracene (1,2-benzanthracene) [56-55-3], benz[< ]acephenanthrylene (3,4-benzofluoranthene) [205-99-2], benzo[ ]pyrene (3,4-benzopyrene, 3,4-BP) [50-32-8], benzo[e]pyrene (1,2-benzopyrene) [192-97-2], perylene [198-55-0], benzo[g,/i,/]perylene (1,12-benzopyrene) [191-24-2], and dibenz[ ,//]anthracene (1,2,5,6-dibenzanthracene) [53-70-3]) cannot be considered as a part of the aroma. However, as some of these, specially benzo[o pyrene, are known for carcinogenic properties, they have been particularly analyzed in food subject to roasting or smoke-curing. [Pg.83]

Table XXIII-5 catalogs the components in the various lists co-authored by Hoffmann. In an attempt at simplification, the seqnence of components in Table XXIII-5 approximates the seqnence in many of the articles. Also in Table XXIII-5, the varions components listed by Hoffmann and colleagues (1727, 1740,1741,1743,1744,1773,1808) are listed in the most recently accepted nomenclatnre, for example, benzo[b]fluoranthene is listed as benz[e]acephenanthrylene, dibenzo[a,/]pyrene is listed as dibenzo[(iej p]chrysene, catechol is listed as 1,2-benzenediol. In each case, the nomenclature used in the Hoffmann articles accompanies the most recent nomenclature listing. Table XXIII-5 catalogs the components in the various lists co-authored by Hoffmann.

Results from many studies have been reported on the types and levels of PAHs, with particular emphasis on B[a]P, B[a]A, chrysene, benz[e]acephenanthrylene (benzo[fc]fluoranthene), benzoMfluoranthene, indeno[l,2,3-C(i]pyrene, DB[fl,/t]A, and benzo[g/t/]perylene. As noted by Menzie et al. (2533), all of these PAHs have been identified in exhausts or effluents from fossil fuel combustion sources, in soils, sediments, and water, and in a variety of commonly used foodstuffs. [Pg.1219]

In 1955, Chardonnens and Ritter isolated the parent [l,2-a]dione 12 through oxidative cleavage of benzo[c]acephenanthrylene (10) using sodium dichromate to generate 2-fluorenonylbenzoic acid (11) followed by ring closure using concentrated sulfuric acid (Scheme 2) [27]. [Pg.162]

Polycyclic aromatic hydrocarbons (PAH) in atmospheric particles have received a great deal of attention because of the known carcinogenic effects of some of these compounds. The most prominent of these compounds is benzo(a)pyrene and other examples are benz(a)anthracene, chrysene, benzo(e)pyrene, benz(e)acephenanthrylene, benzo(j)fluoranthene, and indenol. Some representative structures of PAH compounds are given as follows ... [Pg.186]
