Peroxy sulfate

Chromium (III) tris (ethylenediamine) Peroxy-sulfate in this section... 

Solid Peroxygen Compounds. Hydrogen peroxide reacts with many compounds, such as borates, carbonates, pyrophosphates, sulfates, sihcates, and a variety of organic carboxyHc acids, esters, and anhydrides to give peroxy compounds or peroxyhydrates. A number of these compounds are stable sohds that hydrolyze readily to give hydrogen peroxide in solution. 

Another useful reagent for selenenylcyclization is phenylselenenyl triflate. This reagent is capable of cyclizing unsaturated acids101 and alcohols.102 Phenylselenenyl sulfate can be prepared in situ by oxidation of diphenyl diselenide with ammonium peroxy-disulfate.103... 

Analytical Delicate qual tests for H202 are its reactions with titanic chromate or sulfate in acid to produce the bright blue peroxychromic or bright yellow peroxy titanic acid both of which are sol in ether. Quantitatively H202 may be detd by its oxidation of I- and titration of the I2 (or I3) thus formed (Ref 2)... 

Copper sulfate, CuS04 5H20, is used for the oxidative coupling of terminal acetylenes [5S] for the conversion of a-hydroxy ketones (acyloins) into a-diketones [351, 352] and, in cooperation with potassium peroxy-disulfate, for the selective oxidation of methyl groups on benzene rings to aldehyde groups [355],... 

The regiospecific oxidation of dimethylanisoles to methoxymethyl-benzaldehydes is accomplished with copper sulfate and potassium peroxy-disulfate, which oxidize selectively only the methyls in the ortho or para positions with respect to the methoxy group (equation 171) [35J]. 

Reactions with persulfate and pyrosulfate. The persulfate (peroxy-dlsulfate Ion, S2O8 ) reaction, also known as the Elba persulfate oxidation, has been Important In synthesis of hydroxylated phenols. The method has occasionally been used for synthesis of 0-sulfate conjugates. For example, 4-hydroxy-2-nltrophenyl sulfate was obtained when 3-nltrophenolate was stirred with potassium peroxydlsulfate at room temperature for 2 days (91,). The persulfate reaction has been used for the sulfation of various phenols and aromatic amines however the yields are usually low to moderate (77 ). The sulfate group Is preferentially Introduced In the 4-posltlon of phenols and In the 2-posltlon of aromatic amines but If these positions are blocked substitution at the 2- and... 

Mesityl oxide is oxygenated under irradiation in methanol in the presence of copper(II) sulfate to give a peroxy acetal via photoenolization and stabilization of the s-cis conformation of dienol by Cu(II) the intermediate peroxyhemiacetal undergoes exchange with the solvent to generate the peroxyacetal (Scheme 19) [43]. 

Pyridone, 4-pyridone, and 3-pyridinol undergo the Elbs peroxydisulfate oxidation, a reaction characteristic of phenols and aromatic amines. A bimolecular ionic reaction in which the 2-pyridyloxy ion attacks the peroxy-bond of the persulfate ion with displacement of sulfate ion to give 2-pyridone-5-sulfate is consistent with the observations. ...
