CF3IF2 undergoes fluorine exchange reactions with BX3 (X = Cl, Br, I, OCOCF3) to form the compounds CF3IX2.The reactions of CF3IF2 with (CF3)2BN(CH3)2, (CH3)3SiNCO and (CH3)3SiN(CH3)COCF3 yield the corresponding new trifluoromethyl iodine (III) nitrogen compounds.A preparative method for the synthesis of CF3ICl2 is found by reacting CF3IF2 with (CH3)3SiCl.CF3ICl2 reacts with AgX (X = OCOCF3, SCF3) to yield the corresponding CF3IX2 compounds and with (C6H5)4AsCl the novel ion (-) is detected.Products were identified by n.m.r. spectroscopy.
