Diiododimethylsilane is used as a reducing agent; preparation of N-(iododimethylsilyl)trialkylphosphinimines, bis(2,2-bipyridine) complexes of silicon, di- μ-iodo-bis(tetracarbonyltungsten); chemistry of 7-silanorbornadienes and dimethylsilylene.
Diiododimethylsilane reacts with various ketones in the presence of zinc to give the corresponding reductive condensation products in good yield (eq 2).

8.2 g (21 mmol) of boron triiodide and 7.4 g (57 mmol) of dichlorodimethylsilane are refluxed for 3 days at 120°C; the crude product is then isolated by adding copper powder until the color disappears followed by fractional distillation in a spinning band column apparatus (65% yield).

Diiododimethylsilane reacts vigorously with water, but without spattering; highly toxic, flammable liquid; use in a fume hood.
