Tributyl- and Triphenyltin Benzoates, Phenylacetates, and Cinnamates as Anion Carriers: an Electrochemical Assessment Coupled to Structural NMR Studies and AM1 Calculations

Synthesis and characterization of new polystyrenes containing tributyltin moieties linked to the aromatic ring through a methylenic spacer

“…Nonpolymeric triorganotin compounds, in particular tri‐ n ‐butyltin carboxylates, have been found to be selective species in anion recognition when dispersed in plasticized PVC membranes used as Ion Selective Electrodes6 (ISEs); however, as they are prone to leaching, the immobilization of the organotin moiety onto a polycarboxylic support has previously been achieved, leading to tin functionalized polycinnamates and polystyrenes, where the organometallic residue was spaced from the aromatic ring by a polymethylenic (n = 2, 4) chain 7, 8…”

Anion exchange in trimethyl- and triphenyltin complexes with chromogenic ligands: solution equilibria and colorimetric anion sensing

“…No binding was detected between Bu 3 SnCl and HSO 4 − , but interaction with H 2 PO 4 − was of approximately the same strength as with Cl − . 18 In a more detailed study of chloride binding to a series of compounds R′COOSnR 3 (R = Bu, Ph, R′ = CH 2 Ph, CH = CHPh and their fluorinated derivatives) in CD 2 Cl 2 , the association constants were found to increase from 5–15 M −1 for R = Bu to 100–500 M −1 for R = Ph and to be larger for fluorinated carboxylates for a given R 19. As far as we know there are no data on stability constants for R 3 SnX complexes in organic solvents.…”

Dialkyltin(IV)bis(O–tolyl/benzyldithiocarbonate) complexes: Spectroscopic, thermogravemetric, antifungal and crystal analysis of n–Bu2Sn(S2COCH2C6H5)2

“…Inorganic and organotin compounds have found industrial use as catalysts like in heterogeneous oxidation catalysts based on tin(IV) oxide [1][2] and homogeneous catalysts for industrial organic and polymeric reactions. [3][4] Apart from the well-established uses of tin catalysts in polyurethanes, 5 RTV silicones 6 and esterification reactions, 7 new developments have included their use as anti-tumor drugs, [8][9] ion carriers in electrochemical membrane, 10 in synthetic vitamin E production 11 and in the manufacture of certain novel polymeric materials. 12 A remarkable but little known fact about tin is to save energy and reduce emissions when added to fuel 13 and are effective premixed methane flame inhibitors.…”
