Mercury salt methoxy

The A-chloro compound 176, obtained from the corresponding meth-oxyamide with f-butyl hypochlorite, was cyclized to l-methoxy-2-indolone 163 by silver carbonate in trifluoroacetic acid (87% yield) (84JA5728), or by other silver or mercury salts (87T2577), and more conveniently by anhydrous zinc acetate in 1,2-dichloroethane (91% yield) (87CL1771). The reaction proceeds through the spiro intermediate 177, followed by both possible 1,2-shifts. 

Mercury salts have previously been shown to be capable of cleaving cyclopropyl bonds. Phenyl-substituted cyclopropanes react with mercury(II) acetate to give 3-mercurio-l-methoxy-l-phenylpropane derivatives, which can undergo further reactions such as reduction with sodium borohydride or addition to alkenes. For example, treatment of phenyl-cyclopropane (1) with mercury(II) acetate in methanol, followed by the addition of sodium chloride, produced 3-(chloromercurio)-l-methoxy-l-phenylpropane(2) in good yield.When the primary mercury adduct was reacted with alkenes without isolation, the yields were lower than those in the two-step transformation. ...

To 50 cc of a carefully purified aqueous solution of the sodium salt of N(7-chloromercuri-)3-methoxy-propyl)-d-a-camphoramic acid containing 40 mg of mercury per cc is added 10 cc of a solution containing 1.14 g (1 mol equivalent) of sodium thioglycollate and the mixture is then evaporated to dryness at room temperature and reduced pressure in the presence of a desiccant. The product is an amorphous white powder which decomposes at 156° to 158°C (uncorr,), and which was found on analysis to have a mercury content of 33.0%, according to U.S. Patent 2,576,349.

Holland and Cooper and Wells - comment on a side reaction which leads to the destruction of the photosensitizer and the formation of colored products at low concentrations of alcohol. This reaction may well be the same as that which was observed by Mooney and Stonehill and which was interpreted in terms of photosensitized decomposition of water, with subsequent hydroxylation of the anthraquinone salt. A similar type of reaction was noted by van Beek and Heertjes during their investigation into the chemical and photochemical degradation of anthraquinone mordant dyes in methanol. Irradiation of 3-nitroalizarin in methanol in Pyrex vessels, with visible or ultraviolet light from mercury-vapor lamps, leads to the formation of 4-methoxy-3-nitroalizarin. The methoxylation encountered in this instance would appear to be analogous to the hydroxylation of the sensitizer noted by Mooney and Stonehill, although, it must be pointed out, no such conclusion was drawn by the authors.
