Cyclic voltammetry of thianthrene in the presence of two molar equivalents of pyridine generates thianthrene 5-oxide and not T . Having shown 2-(pyridinium-l-yl)thianthrene to have half wave potentials, 1.45 and 1.74, different from those of thianthrene, the kinetic scheme summarized by Eqs. (16)-(19) was proposed (77JOC976).

Into a boiling agitated solution of 2.44 g pyridine-4-aldoxime in 10 ml absolute ethanol is added dropwise during the course of 25 min a solution of 1.14 g bis-chloromethyl ether in 5 ml absolute ethanol. The reaction mixture is then refluxed for 35 min, and then agitated for 5 h at room temperature. The precipitate of bis-[4-hydroxyimino-methyl-pyridinium-(l)-methyl]-ether-... [Pg.2492]

X-ray analysis of bromo-substituted betaine dye (44) shows that it is not planar. Not only are the five peripheral phenyl groups twisted, but also the pyridinium and phenolate rings, the latter with a mutual interplanar angle of about 65° [75a]. For the X-ray analysis of 4-(2,4,6-triphenyl-pyridinium-l-yl)phenolate [i.e. betaine dye (44) without the two 2,6-phenyl rings at the phenolate moiety), see reference [75bj. In this less substituted betaine dye, the pyridinium/phenolate interplanar angle is 60°. [Pg.425]

Hitherto, there have also been some reports on the use of polymers containing ionic moieties except for polymeric ILs to functionalize CNTs [127-130]. For instance, Yoshida et al. [128] found that a slightly concentrated solution (20 g/L) of an ionic electrolyte of poly(pyridinium-l,4-diyl-iminocarbony 1-1,4-phenylene-methylene chloride) was most appropriate for stable dispersion of SWCNTs in water to form a SWCNT-containing gel. This ionic polymer, capable to act both as a dispersant and as a gelator, may contribute to the development of a novel hydrogel filled with CNTs for the biological, medical, and pharmaceutical applications.
