  Extensive chlorination of methylnaphthalenes, Friedel-Crafts alkylation of pentachlorobenzene by heptachloro(chloromethyl)naphthalenes, and related results

  摘要：

  The chlorination of 2-methylnaphthalene (1) and 1-methylnaphthalene (12) by means of Silberrad's reagent (initial components: SO2Cl2, S2Cl2, and AlCl3) has been performed. From 1 or 12, the following compounds have been synthesized for first time: nonachloro-3-(chloromethyl)-1,4-dihydronaphthalene (3), nonachloro-7-(chloromethyl)-1,4-dihydronaphthalene (4), perchloro-3-vinylindene (2), perchloro-1-vinylindan, nonachloro-4-(chloromethyl)-1,4-dihydronaphthalene (11), heptachloro-7-(chloromethyl)naphthalene (6), heptachloro-8-(chloromethyl)naphthalene (10), heptachloro-7-methylnaphthalene, heptachloro-8-methylnaphthalene, 2-(bromochloromethyl)heptachloronaphthalene, 1-(bromochloromethyl)heptachloronaphthalene, heptachloro-7-formylnaphthalene (24), heptachloro-8-formylnaphthalene (26), (2-heptachloronaphthyl) (pentachlorophenyl)methane (17), and (1-heptachloronaphthyl) (pentachlorophenyl)methane (20). Silberrad's reagent interconverts dihydronaphthalenes 3 and 4. The AlCl3-promoted Friedel-Crafts alkylation of pentachlorobenzene (16) by naphthalenes 6 and 10, giving diarylmethanes 17 and 20, respectively, takes place in mild conditions (refluxing CS2) although the substrate and the alkylating agents are highly crowded polychloro compounds. By heating (100-degrees-C) a mixture of 17, 16, and AlCl3, 1H-heptachloronaphthalene (18) and bis(pentachlorophenyl)methane were obtained. Aldehyde 24, treated with Rh(PPh3)3Cl, gave 2H-heptachloronaphthalene, which was prepared in pure form for the first time. Under similar treatment, aldehyde 26 gave 18. The X-ray structures of indene 2 and dihydronaphthalene 11 are reported and discussed. Some probable mechanisms, as ell as IR, UV, and H-1 NMR spectra data of the compounds synthesized, are presented.
