Figure 6.10. Rate constants for quenching of sensitizers by cis- and trans-stilbenes (open and filled circles, respectively). Sensitizers are as follows (1) tri-phenylene, (2) thioxanthone, (3) phenanthrene, (4) 2-acetonaphthone, (3) 1-naphthyl phenyl ketone, (6) crysene, (7) fluorenone, (8) 1,2,5,6-dibenzanthracene, (9) benzil, (10) 1,2,3,4-dibenzanthracene, (11) pyrene, (12) 1,2-benzanthracene, (13) benzanthrone, (14) 3-acetyl pyrene, (15) acridine, (16) 9,10-dimethyl-l,2-benzanthracene, (17) anthracene, (18) 3,4-benzpyrene.<57> Reprinted by permission of the American Chemical Society.

Naphthyl phenyl sulfide is desulfurized to naphthalene on refluxing with lithium aluminum hydride and titanium tetrachloride, and 1-naphthyl ethyl sulfide and 1-naphthyl isopropyl sulfide are converted to naphthalene on treatment with ethanethiol and anhydrous aluminum chloride (equation 83). ... 

Benz[de]anthrone 272 A finely divided mixture of 1-naphthyl phenyl ketone (1 part) and anhydrous aluminum chloride (5 parts) is heated, with protection by a calcium chloride tube, during 0.5 h from 60° to 115°, during a further 1 h from 115° to 130°, and during a final 1 h from 130° to 150°. The cake is decomposed by dilute hydrochloric acid, and the resulting solid is filtered off and washed with alcohol and ether it then consists of moderately pure benzanthrone (yield 76%). Recrystallization from glacial acetic acid, with charcoal, affords the pure compound as pale brown needles, m.p. 167-168° (uncorr.). 

Scholl reactions generally lead to six-membered rings but a few cases have been reported where five-membered rings were formed, particularly from ketones that carried a hydroxyl or an alkoxyl group para to the carbonyl group, such a case was reported by Fierz-David and Jaccard275 who found that 4-hydroxy-1-naphthyl phenyl ketone (and its methyl ether) gave 5-hydroxy-benzo[a]fluoren-l 1-one and not 4-hydroxybenz[de]anthrone ...
