SeCF2 is prepared on a preparative scale reacting AlI3 with Hg(SeCF3)2 in octamethylcyclotetrasiloxane.It adds MF and Ag> to form MSeCF3.AgSeCF3 was also synthesized from AgF and B(SeCF3)3.Under the influence of sunlight SeCF2 dissolved in CFCl3 dimerizes quantitatively to 2,2,4,4-tetrafluoro-1,3-diselenetane, which above 360 deg C pyrolyses to the monomer.The cyclic dimer reacts with B(SeCF3)3 to give (CF3Se)2CSe.The reaction of AgSeCF3 with CFnCl3-nSCl leads to CF3SeSCFnCl3-n (n = 1, 2, 3).IR, NMR and mass spectra of the newly prepared compounds were presented. - Keywords: Tetrafluoro-1,3-diselenetane, Chemical Reactions, Selenocarbonyldifluorid
