Reaction of trialkylsilanes with iodine and hydrogen iodide

Abstract

1. It was shown that reaction between trialkylsilanes and elementary iodine proceeds in accordance with the equation: 2R3SiH + I2 → 2R3SiI + H2. 2. Five trialkyliodosilanes, three of which were previously unknown, were synthesized in yields of 90 94%. 3. It was found that trialkyliodosilanes can be synthesized in high yield also by reaction between trialkylsilanes and hydrogen iodide, which occurs in absence of catalysts.
