Hydrogen sulfide deserves its bad reputation. It's famous for filling the air of high school chemistry labs with the smell of rotten eggs. One strong whiff of the noxious gas can knock you to the ground. Too much can kill you. However, recent discoveries show that in the right proportions, H2S helps regulate several different bodily functions. In fact, we can't live without it.

The gas phase reactivity of tetrahydofuran (THF) towards a series of anionic bases B(-) = NH2(-), C6H5(-), OH(-), CH2=CH-CH2(-) has been investigated under the low-pressure conditions of a Fourier-Transform Ion-Cyclotron-Resonance (FT-ICR) mass spectrometer. It appears that, under low pressure conditions, the anionic base-induced reactions of THF predominantly proceed by 1,2-elimination. This elimination initially results in rovibrationally excited HB-solvated but-3-ene-l-oxide anions
