  Synthesis of the sterically hindered bis(pentachlorophenyl)acetic acid and derived stable free radicals

  摘要：

  Bis(pentachlorophenyl)acetic acid esters were synthesized from the alpha-hydroxydiaryl acetate esters 13 via the free radicals 15 formed on homolytic cleavage of the alpha-chloro compounds 14. The acid 8 underwent rapid decarboxylation in basic solution (e.g., Et3N in THF) but could be dehydrated to the corresponding ketene 17. Nucleophilic addition to the ketene provided a route to the corresponding amides (21 and 19) and nitrile 20, the enolates of which underwent ready oxidation to the corresponding stable free radicals 15, 22, and 23. Evidence for the structure and unusual stability of these free radicals is presented. Attempts to observe enols of acids or esters on the addition of water or alcohols to the sterically hindered ketene 17 were unsuccessful.

  Chemistry, kinetics, and spectroscopy of highly hindered diarylcarbenes. The case of decachlorodiphenylcarbene

  摘要：

  Bis(pentachlorophenyl)diazomethane (1a) was prepared, and reactivities of perchlorodiphenylcarbene (2a) generated by photolysis of 1a were investigated not only in terms of product analysis but also by using flash photolysis techniques. Although the major reaction found for 2a was dimerization forming perchlorotetraphenylethylene and was essentially similar to that observed for 2,2',4,4',6,6'-hexachlorodiphenylcarbene (2b), product distribution clearly indicated that the carbenic center in 2a is more rigidly protected than that in 2b by the four ortho chloro substituents which are buttressed by the four meta chloro groups. Irradiation of 1a in a 2-methyltetrahydrofuran glass at 77 K resulted in the appearance of the absorption due to triplet 2a at 356, 493, and 525 nm. Flash photolysis of 1a in benzene solution produced a transient absorption due to 2a at 357 nm, which decayed in second order in accordance with the product analysis data. The rate constant for dimerization of 2a was determined to be 2.5 +/- 0.1 x 10(6) M-1 s-1, 3 orders of magnitude smaller than that of unsubstituted diphenylcarbene. The triplet carbene (2a) was trapped by oxygen to generate the perchlorobenzophenone oxide showing its maximum at 390 nm (t1/2 = 510 +/- 9 ms) and also by 1,4-cyclohexadiene to produce bis(perchlorophenyl)methyl radical (lambda(max) 376 nm with the rate constant of 6.2 x 10(3) M-1 s-1.

  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.
