Mercuric benzoate

Mercuric carboxylates, which decarboxylate by a chain mechanism when initiated by peroxides, also decarboxylate under UV irradiation (123,128,129,131-140,142,144-146,153-155). In addition, decarboxylation was observed for mercuric benzoate and mercuric a-naphthoate (123). Side reactions [Eqs. (24), (25), (109)] observed in peroxide initiated reactions also occurred on UV irradiation, and mercurous salt formation [Eq.(24)] was more extensive under the latter conditions. Decarboxylation giving methylmercuric acetate occurred on irradiation of mercuric acetate in aqueous solution and is considered to be of environmental significance (156,157). Stepwise decarboxylation giving (CF3)2Hg occurred on irradiation of solid mercuric trifluoroacetate at -196° C (158), but, at 20° C, trifluoromethyl radicals diffused from the solid and dimerized (158). No other diorganomercurial has been formed by radical decarboxylation, and the reaction is not preparatively competitive with the thermal decarboxylation synthesis of (CF3)2Hg (26,27) (Section III,A). [Pg.269]

Mercuric benzoate is heated in an oil-bath to 270 C. until a test portion gives no precipitate of mercuric oxide when treated with sodium hydroxide. The melt is cooled, powdered, and washed with alcohol and ether to free it from benzoic acid. It is then dissolved in a small amount of dilute sodium carbonate and carbon dioxide passed through the solution, the anhydride being precipitated as a white powder. [Pg.163]

Contrast the effect of heat on mercuric benzoate, when substitution of the aromatic ring ortho to the carboxyl group occurs. Mercuric tri-chloroacetate decar Wylates so rapidly that it has not yet been isolated.
