  2. Mercury(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Mercury(II)_sulfate

    Conversion of 2,5-dimethylhexyne-2,5-diol to 2,2,5,5-tetramethylte-trahydrofuran-3-one. Mercury sulfate, as well as other mercury(II) compounds, are commonly used as catalysts in oxymercuration-demercuration, a type of electrophilic addition reaction that results in hydration of an unsaturated compound. The hydration of an alkene gives an alcohol.

  3. Mercury(II) nitrate - Wikipedia

    en.wikipedia.org/wiki/Mercury(II)_nitrate

    Mercury(II) nitrate is an inorganic compound with the chemical formula Hg(N O 3) 2. It is the mercury(II) salt of nitric acid HNO 3. It contains mercury(II) cations Hg 2+ and nitrate anions NO − 3, and water of crystallization H 2 O in the case of a hydrous salt. Mercury(II) nitrate forms hydrates Hg(NO 3) 2 ·xH 2 O.

    en.wikipedia.org/wiki/Solvent_effects

    The case for S N 2 reactions is quite different, as the lack of solvation on the nucleophile increases the rate of an S N 2 reaction. In either case (S N 1 or S N 2), the ability to either stabilize the transition state (S N 1) or destabilize the reactant starting material (S N 2) acts to decrease the ΔG ‡ activation and thereby increase the ...

    The sulfonyl functional group (RS(O) 2 R') has become an important electron-withdrawing group for modern organic chemistry. α-Sulfonyl carbanions may be used as nucleophiles in alkylation reactions, Michael-type additions, and other processes. [3] After having served their synthetic purpose, sulfonyl groups are often removed.

  7. Fenton's reagent - Wikipedia

    en.wikipedia.org/wiki/Fenton's_reagent

    Fenton's reagent is a solution of hydrogen peroxide (H 2 O 2) and an iron catalyst (typically iron(II) sulfate, FeSO 4). [1] It is used to oxidize contaminants or waste water as part of an advanced oxidation process. Fenton's reagent can be used to destroy organic compounds such as trichloroethylene and tetrachloroethylene (perchloroethylene

  8. Mercury (II) thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Mercury(II)_thiocyanate

    The decomposition of Hg(SCN) 2 is exothermic on its own, and the CS 2 produced ignites easily and burns off. The C 3 N 4 product is a simplification; the actual product contains 0.5% hydrogen and is likely to consist of sheets of triazine rings linked by −N= and −NH− groups similar to g−C 3 N 4 and was found to contain nano-particles of ...

  9. Mercury (I) nitrate - Wikipedia

    en.wikipedia.org/wiki/Mercury(I)_nitrate

    Mercury(I) nitrate is an inorganic compound, a salt of mercury and nitric acid with the formula Hg 2 (NO 3) 2. A yellow solid, the compound is used as a precursor to other Hg 2 2+ complexes. The structure of the hydrate has been determined by X-ray crystallography. It consists of a [H 2 O-Hg-Hg-OH 2] 2+ center, with a Hg-Hg distance of 254 pm. [3]
