bp 170°C; d 2.203 g cm?3. | [Uses]
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). | [Preparation]
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). | [Precautions]
Diiododimethylsilane reacts vigorously with water, but without spattering; highly toxic, flammable liquid; use in a fume hood. |
