Description
BENZENESELENINIC ANHYDRIDE is a white to light beige powder that is known for its mild oxidizing properties. It is a chemical compound that is used in various chemical reactions, particularly in the oxidation of phenols and the conversion of benzylic hydrocarbons into aldehydes or ketones. It is also used to oxidize hydrazines to produce azo-compounds.
Uses
Used in Chemical Synthesis:
BENZENESELENINIC ANHYDRIDE is used as a mild oxidizing agent for the conversion of benzylic hydrocarbons into aldehydes or ketones. This application is particularly useful in the synthesis of various organic compounds, as it allows for the selective oxidation of specific functional groups without affecting others.
Used in the Production of Azo-Compounds:
BENZENESELENINIC ANHYDRIDE is used as an oxidizing agent for the conversion of hydrazines to azo-compounds. This process is important in the synthesis of a wide range of azo-compounds, which have various applications in the chemical, pharmaceutical, and materials science industries.
Used in the Oxidation of Phenols:
BENZENESELENINIC ANHYDRIDE is used as an oxidizing agent for the oxidation of phenols to ortho-quinones. This reaction is significant in the production of various quinone-based compounds, which are used in the synthesis of dyes, pharmaceuticals, and other specialty chemicals.
Purification Methods
When the anhydride is recrystallised from *C6H6 it has m 124-126o, but when this is heated at 140o/1hour in a vacuum or at 90o/2hours it has m 164-165o and gives a solid m 124-126o when then recrystallised from *C6H6. Both depress the melting point of the acid PhSeO2H. If the high melting anhydride is dissolved in *C6H6 and seeded with the high melting anhydride, the high melting anhydride crystallises out. It readily absorbs H2O to form the acid (PhSeO2H, m 122-124o). Because of this the commercial anhydride could contain up to 30% of the acid. It is best purified by converting to the HNO3 complex (m 112o) and heating this in vacuo at 120o/72hours to give the anhydride as a white powder m 164-165o. Alternatively heat the anhydride in vacuo at 120o/72 hours until the IR shows no OH band. [Ayvrey et al. J Chem Soc 2089 1962, Barton et al.

Check Digit Verification of cas no
The CAS Registry Mumber 17697-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,9 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17697-12:
(7*1)+(6*7)+(5*6)+(4*9)+(3*7)+(2*1)+(1*2)=140
140 % 10 = 0
So 17697-12-0 is a valid CAS Registry Number.

t-Butyl benzeneperoxyseleninate, PhSe(O)OOBut, has been prepared by the reaction of t-butyl hydroperoxide with PhSe(O)OSe(O)Ph or PhS(O)OEt, and of sodium t-butyl peroxide with PhSe(O)Br.Formation of the less stable analogues p-MeC6H4Se(O)OOBut and BuSe(O)OOBut from t-butyl hydroperoxide and the corresponding seleninyl anhydrides has been confirmed by 13C n.m.r. spectroscopy.
