说明

Application

Ba(CF₃SO₃) can be utilized as a precursor to synthesize:

Alkali metal and silver trifluoromethanesulfonates.
Sodium trifluoromethanesulfonate (sodium triflate) by reacting with sodium sulfate. Sodium triflate finds application in organic synthesis as an efficient catalyst as well as a reactant in catalytic asymmetric Mannich-type reactions, and Diels-Alder reactions.

Sodium 1, 1, 1-Trifluoromethanesulfonate

Surya Prakash GK and Mathew T

Encyclopedia of Reagents for Organic Synthesis, Second Edition (2001)

On the relationship between the structural and volumetric properties of solvated metal ions in O-donor solvents using new structural data in amide solvents.

Daniel Lundberg et al.

Physical chemistry chemical physics : PCCP, 20(21), 14525-14536 (2018-05-17)

The structures of the N,N-dimethylformamide (dmf), N,N-dimethylacetamide (dma), and N,N-dimethylpropionamide (dmp) solvated strontium and barium ions have been determined in solution using large angle X-ray scattering and EXAFS spectroscopy. The strontium ion has a mean coordination number (CN) between 6.2

Cu(OTf)2-catalyzed synthesis of 2,3-disubstituted indoles and 2,4,5-trisubstituted pyrroles from α-diazoketones.

B V Subba Reddy et al.

Organic letters, 15(3), 464-467 (2013-01-18)

A novel method has been devised for the synthesis of 2,4,5-trisubstituted pyrrole derivatives through the coupling of α-diazoketones with β-enaminoketones and esters using 10 mol % of Cu(OTf)(2). A wide range of 2,3-disubstituted indole derivatives were also prepared from α-diazoketones
