3,4-Bis(trifluoromethyl)-1,2-dithiete

3,4-Bis(trifluoromethyl)-1,2-dithiete is the organofluorine compound with the formula (CF3)2C2S2, a yellow liquid.

[1] Being planar with six pi-electrons, the compound is considered to be aromatic.

This description is supported by an electron diffraction study,[2] which reveals an elongated C=C distance of 1.40 Å and shortened C-S distances of 1.73 Å.

The compound tends to dimerize at room temperature, but the dimer cracks at higher temperature back to the dithiete.

It reacts with low valent metal complexes by oxidative addition:[3]
