Synthesis of polymethine dyes from 1-(3-chloro-2-tetrahydrofuryl)-4-methylquinolinium chloride

Synthesis of polymethine dyes from 1-(3-chloro-2-tetrahydrofuryl)-4-methylquinolinium chloride. Simbera, J.In this experiment, several chemicals are used like 67189-99-5 ; Pichler, J.; Ciernik, J. (Dep. Org. Chem., Jana Ev. Purkyne Univ., Brno, Czech. 67189-99-5 are also occured in this study.). Scr. Fac. Sci. Nat. Univ. Purkynianae Brun., 8(3), 77-87 (English) 1978. CODEN: SUPBAA. ISSN: 0371-4144. DOCUMENT TYPE: Journal CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) 1-(3-Chloro-2-tetrahydrofuryl)-4-methylquinolinium chloride [67189-99-5], prepd. by reaction of HCl-free 2,3-dichlorotetrahydrofuran [3511-19-1] with 4-methylquinoline [491-35-0], was treated with HC(OEt)3, 3-ethyl-2-(ethylthio)benzothiazolium p-toluenesulfonate [5231-22-1], 1-ethyl-2-(ethylthio)quinolinium chloride [67190-01-6], 1-ethyl-2(ethylthio)-6-methylquinolinium chloride [67190-02-7], or 5-(anilinomethylene)-3-ethylthiazolidine-2-thion-4-one [39542-83-1] to give mono-, di-, or trimethinecyanine dyes, the absorption spectra and photog. sensitizing properties of which were studied. Absorption max. were essentially the same as those of the corresponding 1-ethylquinoline analogs, showing that the 3-chloro-2-tetrahydrofuryl group has no effect on their optical properties. Dyes I [67190-05-0] and II [67190-06-1] showed av. sensitizing efficiency and a slightly above-av. tendency to fog photog. emulsions. ..

Reactions of chlorinated tetrahydrofurans

Reactions of chlorinated tetrahydrofurans. XIX. Polychlorination of chlorotetrahydrofurans. Slais, K.; Vanicek, M. (Inst. 3511-19-1 which is the cas registry number is also used here. Anal. Chem., Czech. Acad. Sci., Brno, Czech.). Chem. Zvesti, 31(1), 109-17 (English) 1977. CODEN: CHZVAN. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 22 Polychlorination of THF was studied using gas chromatog., high resoln. liq. chromatog., and NMR. Pathways of polychlorination depending on the reaction temp. and intensity of the UV irradn. were proposed. Some of the pathways can be used to prep. the polychloro derivs. E.g., chlorination of 2,3,3-tetrachlorotetrahydrofuran without radiation gave I; with radiation II and III are obtained.Except for chemicals metioned above, 3511-19-1 is also used. ..
