Trimethylsilyl 3-Nitrobenzenesulfenate is a chemical compound with the molecular formula C9H11NO5SSi. It is a derivative of 3-nitrobenzenesulfenic acid, where the hydrogen atom is replaced by a trimethylsilyl group. This modification enhances the reactivity and stability of the molecule, making it a valuable intermediate in organic synthesis. The compound is characterized by its ability to act as a nucleophile and a leaving group, which is useful in various chemical transformations, such as the formation of carbon-sulfur bonds. It is also known for its potential applications in the synthesis of pharmaceuticals and agrochemicals, where its unique reactivity profile can be exploited to construct complex molecular structures.

Check Digit Verification of cas no

The CAS Registry Mumber 73116-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,1 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73116-71:
(7*7)+(6*3)+(5*1)+(4*1)+(3*6)+(2*7)+(1*1)=109
109 % 10 = 9
So 73116-71-9 is a valid CAS Registry Number.

Chemistry of Sulfenic Acids. 1. Synthesis of Trimethylsilyl Arenesulfenates (Arenesulfenic Acids)

Davis, Franklin A.,Rizvi, Syed Q. A.,Ardecky, Robert,Gosciniak, Donald J.,Friedman, Arthur J.,Yocklovich, Steven G.

, p. 1650 - 1653 (1980)

Trimethylsilyl arenesulfenates (5), masked sulfenic acids, are prepared in low yield by trapping the intermediate arenesulfenic acid generated by thermolysis of the corresponding N-benzylidenarenesulfinamide (4) with chlorotrimethylsilane-hexamethyldisilazane.Attempts to prepare 5 by oxidation of trialkyl(phenylthio)silanes (8) with 2-(benzenesulfonyl)-3-phenyloxaziridine (11), an aprotic oxidizing reagent, gave instead the previously unknown trialkylsilyl benzenesulfinates (12).These results are attributed to the enhabced nucleophilicity (α effect) of the intermediate trialkylsilyl arenesulfenate ester.
