Mercuration of nitrophenols and numerous compounds that might be taken as their derivatives with mercury acetate or oxide were carried out and the effect of the reaction of the solution was followed, in order to examine the relationship between the structures of the compounds during this reaction and of the mercury compounds formed.
2-Nitrophenol (color change in the range of pH 5-7) and 4-nitrophenol (-do-, pH 5.6-7.6) are capable of being mercurated at pH 3.6-8 and respectively form 4, 6- and 2, 6-dimercuri compounds. 3-Nitrophenol (-do-, pH 6.8-8.6) can be mercurated at around pH 3-10, forming only the 4, 6-dimercuri compound at around pH 3 and a mixture of 4- and 6-mercuri compounds at around pH 10, indicating smaller tendency to form the dimercuri compound with the increasing value of pH.
The position of the substituted mercury in these series of mercury compounds was determined by the substitution of mercury with iodine and the homogeneity of the mercury compounds was examined by paper chromatography, using a mixture of 1:2:7 volumes of 10% phenol, N sodium hydroxide, and water, as the developing solvent.
