Indium trifluoromethanesulfonate

Indium trifluoromethanesulfonate was found to be an effective high-yielding catalyst for the facile dehydration of aldoximes to nitriles and Beckmann rearrangement of ketoximes to anilides. ... 

N,iV-Disulfonyl ynamides react with salicylaldehydes through a keteni-mine intermediate in the presence of triethylamine giving access to 3-substituted iminosulfonylcoumarins (140BC3986). Biscoumarins fused at the pyrone ring arise from the indium(III) trifluoromethanesulfonate-catalyzed reaction of methyl coumarin-3-carboxylate with phenols, in good yields (14JOC8723). A library of 3,3 -biscoumarin-based protein kinase inhibitors is achieved from the condensation of 2 -hydroxyacetophenones... 

Alkylation and Allylation. The use of TBAT as a fluoride source for the in situ formation of pentacoordinate silicates from silanes of alkyl and allyl substituents, generating electron-rich carbon centers capable of acting as nucleophiles toward electron deficient moieties, has been well documented for over a decade. Recently, A-acylhydrazones have been shown to undergo highly diastereoselective allylations when treated with allylsilanes, TBAT, and indium(III) trifluoromethanesulfonate (eq 10). ... 

Lanthanum trifluoromethanesulfonate was shown to promote an indium-mediated vinylogous Reformatsky coupling in water (Diana et al., 1996) ...

In the devices described here, we utilized the simplest sandwich structure for the device configuration with p>oly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT-PSS) coated indium-tin-oxide (ITO) glass as the anode and aluminum as the cathode. The well-known soluble phenyl-substituted polyfpara-phenylene vinylene) (PPV) copolymer ("superyellow" from Merck/Covion) (Spreitzer et al., 1998) was selected as our host light-emitting polymer and an organic ionic liquid, methyltrioctylammonium trifluoromethanesulfonate (MATS), was used to introduce a dilute concentration of mobile ions into the emitting polymer layer.
