Radical reaction producing strange results. Can anyone help?
« on: September 23, 2015, 01:13:34 PM »
After running a gas phase reaction of dilute tetrafluoroethene in excess chlorine some strange IR peaks showed up. The reactants were placed in the measurement cell and then exposed to long wave UV light with the FTIR taking the full spectrum every minuet for 10 minuets. At about the second minuet the reactant peaks disappeared and two new product peaks appeared at 1250cm-1 and 1950cm-1. The products remained stable for the duration of the IR measurement, so the products are, at least relatively, stable.

I cant figure out what these products could be. Does anyone know of a good spectral database that I could look through, or does anyone have any ideas as to what the product could be? Any help would be appreciated!

Sometime when you're not dancing, could you post images of the spectra?

Sorry for the late reply, heres the spectrum. We are thinking it is a difluorocarbonyl

Sorry if the picture is hard to read I had to shrink it considerably to meet the upload requirements

Looks like COF2, though this spectrum is massively saturated:
