Silver-catalyzed C-H trifluoromethylation of arenes using trifluoroacetic acid as the trifluoromethylating reagent.

Guangfa Shi et al.

Organic letters, 17(1), 38-41 (2014-12-18)

Direct trifluoromethylation of arenes using TFA as the trifluoromethylating reagent was achieved with Ag as the catalyst. This reaction not only provides a new protocol for aryl C-H trifluoromethylation, but the generation of CF3· from TFA may prove useful in

Highly sensitive reduced graphene oxide impedance sensor harnessing π-stacking interaction mediated direct deposition of protein probes.

Kwang Su Kim et al.

ACS applied materials & interfaces, 5(9), 3591-3598 (2013-04-05)

Graphene-based electrochemical impedance sensors have recently received much attention due to their outstanding sensing capability and economic viability. In this study, we present a novel means of constructing an impedance sensing platform via harnessing intrinsic π-stacking interactions between probe protein

Separation of large denatured peptides by reverse phase high performance liquid chromatography. Trifluoroacetic acid as a peptide solvent.

W C Mahoney et al.

The Journal of biological chemistry, 255(23), 11199-11203 (1980-12-10)

A method employing reverse phase high performance liquid chromatography has been developed for the purification of large denatured peptides. The cyanogen bromide fragments of hemoglobin alpha, beta, and gamma chains (13 to 91 residues in length) could be separated and
