Note Tertiary amines and quaternary ammonium compounds yield stronger colors than primary amines [25]. The dipping solution can also be used as spray solution [44]. Other reagent compositions have also been reported in the literature (1, 3, 6, 12, 13, 15, 18, 21, 23, 41] In some cases the reagents have been made up in acetone [38, 39], methanol [14] or ethanol [37] and/or acidified with hydrochloric acid [3, 33, 37-40]. The concentrations of hexachloroplatinic(IV) acid have been in the range of 0.05 -0.4 those of potassium iodide between 0.5 and 24spray solution containing 2% potassium iodide and 0.23170 hexachloroplatinic(IV) acid hexahydrate in N-hydro-chloric acid is reported to yield the best coloration results with respect to detection sensitivity and color differentiation in the detection of morphine, codeine, quinine, methadone and cocaine [46]. Acidic reagent solutions have been recommended for benzodiazepines [10, 11]. Sulfones do not react [39]. 

Boiling ammonium hexachloroplatinate with alkali gives a product (possibly potassium hexahydroxyplatinate) which after drying will explode violently on heating alone or with combustible materials.

Evaporation of a solution of hexachloroplatinic acid with a deficiency of potassium azide, or with an equivalence of ammonium azide gives explosive residues. Evaporation of a solution of the acid with an equivalence (8 mol) of potassium azide leads to explosion of the cone, solution of the title compound.

None of the accepted preparative methods12 for disodium hexa-chloroplatinate(IV), Na2[PtCl6], is entirely suitable for routine use, because these procedures require reaction of a mixture of solid sodium chloride and platinum metal with chlorine gas at temperatures near 500°. However, a preparation of the desired compound is described below which yields a product of very high purity and which is much more convenient than those previously reported since only solution chemistry is involved. Unlike the corresponding ammonium and potassium salts, disodium hexachloroplatinate(IV) exhibits high solubility in water and in several nonaqueous solvents, including ethanol, methanol, and Ar,/V-dimethylformamide—a fact which enables one to extend the range of studies of the chemistry of hexachloroplatinate(IV).

Two pigments belong to this general group, both are halides a palladium ammonium chloride ( ammonia-perchloride of palladium or palladium red ) and potassium hexachloroplatinate(lV), K2[PtClg] (also known as potassium chloroplatinate), which may be associated with the rare pigment known historically as platina yellow .

Carboxylic acids and their salts, as well as alcohols and alkoxides, are common ligands and this has limited their use as reductants in synthesis. Potassium hexachloroplatinate(IV), for example, is reduced by ammonium oxalate.63 Che and coworkers 4 have shown that the reaction of aqueous solutions of ascorbic acid with the complex, [Ru02(NH3)4]Cl2, in the presence of NaX (X = Cl, I, CNS) yields the complexes, [RuX2(NH3)4]X. The reduction of a mixture of hydrated ruthenium(III) chloride and ruthenium(IV) chloride by glucose or ascorbic acid in water in the presence of 2,2 -bipyridyl results in the formation of [Ru(bipy)3]Cl2 7H20. 5 Additionally, the reduction of the [Tc04] anion by gluconic acid has been studied. ...
