Stannane, triphenyl[(trichloroacetyl)oxy]-, also known as triphenylstannane trichloroacetate, is a chemical compound with the molecular formula C20H15Cl3O2Sn. It is a derivative of triphenylstannane, where one of the hydrogen atoms is replaced by a trichloroacetyloxy group. This organotin compound is characterized by its ability to act as a Lewis acid and a reducing agent in various chemical reactions. It is often used in organic synthesis, particularly in the formation of carbon-carbon bonds and the reduction of carbonyl compounds. Due to its reactivity and potential toxicity, it is important to handle Stannane, triphenyl[(trichloroacetyl)oxy]- with care, following appropriate safety protocols.

7546-90-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7546-90-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,4 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7546-90:
(6*7)+(5*5)+(4*4)+(3*6)+(2*9)+(1*0)=119
119 % 10 = 9
So 7546-90-9 is a valid CAS Registry Number.

Cleavage of tin-aryl bond(s) by monohalocarboxylic acids : The steric factor role

Chauhan,Mishra, Shafalika,Sharma, Rita,Srivastava

, p. 255 - 264 (2008/10/09)

All four tin-carbon bonds of tetra-p-tolyltin can be successively cleaved by iodoacetic acid. Reactions with tetra-m-tolyltin are sluggish and only one tin-carbon bond is cleaved, even in the presence of an excess of the acid. Tetra-o-tolyltin does not react under similar conditions. Steric factors are thought to be responsible for this difference in reactivity of tetratolyltins. The monocarboxylates were not isolated in case of Ph4Sn (except with CCl3COOH). Tetraphenylgermanium gives only the monocarboxylates Ph3GeOOCR′, (R′ = CH2Cl, CH2Br, CH2I), but all the Ph-Pb bonds in tetraphenyllead may be successively cleaved. Tri-p-tolyltin chloride reacts with iodoacetic acid to give a mixed chloro halocarboxylate, (p-MeC6H4)2SnCl(OOCCH2I), but attempts to prepare a mixed carboxylate by reacting (p-MeC6H4)3SnOOCCH2Cl with HOOCCH2I failed.

Molecular Adducts of Triphenyltin Trichloroacetate

Srivastava, T N,Singh, Jaideo

, p. 674 - 676 (2007/10/02)

Triphenyltin trichloroacetate has been prepared by interaction of triphenyltinhydroxide with trichloroacetic acid in 2,2'-dimethoxypropane.Its acceptor property towards various -N, -O and -S donor Lewis bases has been studied and several new molecular adducts have been isolated and characterised.Physicochemical data suggest the presence of unidentate carboxyl group in the compounds.
