16836-95-6 Usage


Silver p-toluenesulfonate, also known as silver tosylate, is an inorganic compound with the chemical formula Ag(p-Ts)O3S. It is a white to light grey crystalline powder that is widely used in organic synthesis as a reagent. It is known for its ability to promote the leaving ability of halogens, making it a valuable tool in various chemical reactions.


Used in Organic Synthesis:
Silver p-toluenesulfonate is used as a reagent for the conversion of alkyl halides to alkyl tosylates. This application is particularly useful in organic synthesis, as it allows for the formation of new chemical bonds and the creation of a variety of complex molecules.
Used in Promotion of Leaving Ability of Halogens:
Silver p-toluenesulfonate is also used to enhance the leaving ability of halogens in chemical reactions. This property makes it a valuable tool in the synthesis of various organic compounds, as it can facilitate the formation of new bonds and improve the overall efficiency of the reaction.
Used in the Conversion of Benzyl Selenyl Chlorides:
In addition to its use with alkyl halides, silver p-toluenesulfonate is also used in the conversion of benzyl selenyl chlorides into their corresponding selenyl tosylates. This application further demonstrates the versatility of this reagent in organic synthesis, as it can be applied to a range of different chemical reactions and transformations.

Purification Methods

The anhydrous salt is obtained by recrystallisation from H2O. Store it in the dark. [Claesson & Wallin Chem Ber 12 1851 1879, Beilstein 11 H 97, 99.]

Check Digit Verification of cas no

The CAS Registry Mumber 16836-95-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,3 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16836-95:
136 % 10 = 6
So 16836-95-6 is a valid CAS Registry Number.

Nonaqueous preparation of stable silver nanoparticles dispersions from organic sulfonic acids

Glushko, Valentina,Blokhina, Lidiya,Sadovskaya, Natalya,Kozhukhov, Vadim

, p. 789 - 797 (2016)

The conditions for stable silver nanoparticles dispersions synthesis from organic sulfonic acids in an anhydrous medium of ethylene glycol and its methyl ester were studied. Ascorbic acid and potassium citrate were used as reducing agents.

An unusual diverse coordination of silver(I) with N-allylthiohydantoin ligand in the presence of benzene- and p-toluenesulfonate anions

Fedorchuk,Slyvka, Yu.I.,Kinzhybalo,Lis,Mys'kiv

, p. 79 - 86 (2019)

Crystalline silver(I) coordination compounds [Ag2(HL)4(C6H5SO3)2]·0.5C3H7OH (1) and [Ag2(HL)(L)(CH3C6H4SO3)] (2) (HL = 3-(prop-2-en-1-yl)-2-thioxoimidazolidin-4-one) have been obtained using silver(I) salts and the organic ligand HL. Three independent Ag(I) atoms in crystal 1 adopt exclusively different coordination environment: tetragonal pyramidal, seesaw and distorted tetrahedral. In crystal 2 metal ions coordination polyhedra are characterized by seesaw and distorted tetrahedral arrangements. Thiohydantoin molecules in both structures are attached to Ag(I) only through thiohydantoin S-atom, while its anionic form in 2 plays a role of N,S-linker. C6H5SO3? anions in 1 are bound to the Ag(I) ions in a bridging mode, connecting silver ions into serpentine-like {Ag4(C6H5SO3)4}n chains, within which silver ions are additionally bind with μ2-S atoms of HL. Simultaneous coordination of HL and L? moieties in polymeric chains of 2 allow the formation of Ag….Ag metallophilic interactions with the distance range of 2.99–3.13 ?.
