General description

2,2,2-Trifluoroethanethiol is a fluorinated thiol. The microwave spectrum of 2,2,2-trifluoroethanethiol, and its deuterated species, CF3CH2SD has been studied. The gas phase acidity and basicity of 2,2,2-trifluoroethanethiol (TFET) has been investigated by Fourier transform ion cyclotron resonance spectroscopy. Reaction of 2,2,2-trifluoroethanethiol on Mo(110) surface was studied using temperature-programmed section, Auger electron and infrared spectroscopies.
2,2,2-Trifluoroethanethiol is basic in nature and forms charge transfer complexes with molecular iodine.
