Seheuing and Winterhalder treated 2 6-distr3rrylpyridine tetra-bromide with potassium hydroxide in alcohol, so producing 2 6-di-)3-phenylacetylenylpyridine (XI) which by the action of 50 per cent, sulphuric acid was converted into 2 6-diphenacylpyridine (XII), and this, on hydrogenation in presence of platinic oxide, barium sulphate and methyl alcohol, was reduced to 2 6-di-(6-hydroxy-(6-phenylethylpyridine, and the hydrochloride of this, on similar catalytic hydrogenation, yielded worlobelanidine (XIII). This can be methylated to lobelanidine, from which in turn dMobeline and lobelanine can be obtained. [Pg.25]

Nicotine may be detected by the colourless, crystalline mercurichloride obtained when an aqueous solution is added to a solution of mercuric chloride, by the black precipitate formed under similar conditions with potassium platinic iodide and the characteristic crystalline periodide, BI2. HI, m.p. 123°, produced on admixture, under specified conditions, 2 of ethereal solutions of nicotine and iodine (cf Anabasine, p. 43). A polarographic study of nicotine has been made by Kirkpatrick. ... [Pg.37]

Conversion of sulfur dioxide to trioxide requires a suitable catalyst. Vanadium pentoxide, V2O5, is probably the most effective catalyst for the contact process. Vanadium and potassium salts supported on diatomaceous earth, platinized asbestos, platinized magnesium sulfate, and ferric oxide also have proved to be efficient catalysts. [Pg.901]

The metallic character of the cation-deficient partially oxidized tetracyano-platinate complexes is of considerable interest because of their unusual anisotropic electrical properties. The method used in the preparation of these compounds is a modification of the procedure used by Levy1 and gives a higher yield of pure product than the syntheses previously described in the literature2 5 (only the potassium compound has been reported to date). [Pg.6]

In addition to the partially oxidized tetracyanoplatinates, bis(oxalato)platinate-(II) can be nonstoichiometrically oxidized by chemical oxidants13 to form highly lustrous needlelike crystals containing platinum in the 2.36 oxidation state. These complexes have not been characterized to the extent of the tetracyano-platinate complexes however, the oxalato complexes are reported to be highly conducting.13 The starting material is bis(oxalato)platinate(II), which can be prepared in 30% yields from hexachloroplatinate(lV) and potassium oxalate.9...

Tetrammino-platinous Hydroxide, [Pt(NH3)4](OH)2, the base of the series, is isolated by treating a solution of tlie sulphate with baryta. The liquid is filtered and evaporated in vacuo, when the hydroxide separates in white deliquescent needles. It is a strong base, absorbs carbon dioxide from the air, displaces ammonia from its salts, and precipitates metallic hydroxides from solution of their salts. It decomposes at 110° C., and ammonia is not liberated from it by potassium hydroxide. [Pg.227]

Dipropylenediamino-platinous Chloride, [Pt pn2]Cl2, crystallises in greyish-white leaflets, and is prepared by boiling a solution- of potassium chloroplatinite with propylenediamine under a reflux until the yellow precipitate first formed dissolves. [Pg.228]
