A mixture of [( Me CAACN)2CH + ][TfO -] (90 mg, 0.12 mmol) and K[N(SiMe3)2] (24 mg, 0.12 mmol) in a vial was cooled to -40 ºC in the glovebox. THF (3 mL) at -40 ºC was added to the mixture to form an orangered solution which was stirred for 5 minutes. I2 (30 mg, 0.12 mmol) was added, and the resulting mixture was allowed to stir for an additional 5 minutes before warming up to room temperature. Volatiles were removed in vacuo and solids were dissolved in CDCl3 for 1 H NMR. [( Me CAACN)2CI + ][I -] was not isolated.
