Phenyl mercuric iodide

Mercury diphenyl has been prepared in a number of ways. The most important methods are by the action of sodium on a mixture of bromobcnzene and mercuric chloride 1 from sodium amalgam and phenyl mercuric iodide 2 by the interaction of phenyl mercuric bromide and potassium sulfide2 or phenyl mercuric acetate and sodium stannite 3 from phenyl magnesium bromide and mercuric chloride 4 by the action of phenyl hydrazine on mercury compounds 5 from mercuric chloride and phenyl arsenious oxide 6 and from diphenyl mercuric ammonium acetate and sulfur compounds.7... [Pg.85]

Seyferth concludes that phenyl(lrifluoromethyl)mercury is an excellent precursor for difluorocarbene. In the general procedure, 1 molar eq. of CeHjHgCFj, 2.5-3.0 molar eq. of well-dried sodium iodide, and 3.0 molar eq. of the dried olefin are used (N2). Benzene is distilled into the reaction flask directly from sodium benzophenone ketyl. The reaction mixture is stirred and heated at reflux under Nj for 12 18 hr. Filtration removes phenyl mercuric iodide and Nal and Nab" the gem-difluorocyclo-propanes are isolated by distillation or by gas chromatography, usually in good yield. [Pg.384]

Sulfoxides are known to form both 0-alkyl and S-alkyl derivatives. The latter are obtained when so-called soft alkylating agents are employed. This behavior of sulfoxides was utilized (172) in the stereospecific synthesis of chiral 135. The reaction of the optically active (+)-ethyl phenyl sulfoxide 136 with methyl iodide in the presence of mercuric iodide followed by anion exchange was found to give the optically active salt 135. [Pg.373]

Classification Specially denatured alcohol Definition Ethyl alcohol (100 gal) denatured with (1) potassium iodide USP (80 g) and red mercuric iodide NF (109 g), or (2) thimerosal USP (95 g) or (3) 76 g of any of phenyl mercuric nitrate NF, phenyl mercury chloride NF, or phenyl mercury benzoate... [Pg.3889]

A reaction formally similar to /3-phenyl assisted solvolysis is deoxy-mercuration of /S-methoxyethyl mercuric iodide, for which Kreevoy and Ditsch (167) cite strong independent evidence in favor of a protonation pre-equilibrium followed by elimination of methanol assisted by Hgl participation ... [Pg.206]

The actual isolation of beryllium dialkyls in a pure state has only just been accomplished by Gilman and Schulze, and their work throws doubt upon the accurac of that of previous investigators. Their method of procedure is the one suggested by Krause and Wendt. In 1926, Durand claimed to have prepared beryllium methyl iodide, but the work has since been disproved by Gilman and Schulze. These workers have isolated beryllium alkyl halides by heating beryllium, alkyl halides, and ether in the presence of catalysts, such as mercuric chloride, beryllium chloride, or free bromine. The first aryl compound, beryllium phenyl iodide, has been prepared by a similar process. [Pg.12]

Beryllium phenyl iodide, Be(CeHg)I, gives a positive test when prepared in the presence of mercuric chloride after fifteen hours heating at 80° to 90° C., and is also readily prepared by heating at 150° to 175° C. with either mercuric or beryllium chloride as catalyst. [Pg.15]

Although thienyl compounds of the type RHgX react with potassium iodide in acetone to give the type R Hg, this has only been noted in benzenoid derivatives in the case of p-tolylmercuric chloride, when a large excess of potassium iodide is used. With phenyl and a-naphthyl-mercuric chlorides only the corresponding iodides are produced. The... [Pg.71]

Treatment with moist silver oxide gives a solution of the corresponding hydroxide dry silver oxide does not yield an oxide but decomj)oses the chloride with formation of mercury diphenyl, mercuric oxide, and silver chloride. When an acetone solution of phenylmercuric chloride is treated with a similar solution of sodium iodide, phenylmercuric iodide is formed." Arsenic trichloride heated at 100° C. for four to five hours with the chloride delds phenyl dichloroarsine. With phenyl iododichloride it yields mercuric chloride and diphenyl iodonium chloride. Ethyl mercaptan decomposes phenylmercuric chloride at 150° 0. jitlding ethyl thio-mercurie chloride, ClHg.SEt. ... [Pg.88]

A few mercurated 3-pyrazolin-5-ones have been prepared by Ragno1155 (Table XXXIX). Antipyrine was treated with mercuric acetate or mercuric ammonobasic chloride, giving mercury-containing substituents in the 4-position. The chloromercuri and acetoxymercuri compounds obtained were converted into others by treatment with hydrochloric acid, potassium bromide, potassium iodide, iodine or sodium hydroxide. More vigorous treatment with mercuric acetate introduced a second acetoxymercuri substituent which was in the phenyl ring. [Pg.123]
