The Reaction between Sulfur Dioxide and Hexamethyldisilazane. 2. Oxygen Atom Transfer from Sulfur Dioxide

Published

Journal Article

The new reaction between sulfur dioxide and hexamethyldisilazane, which forms ((CH 3 ) 3 Si) 2 O, (CH 3 ) 3 SiNSO, and NH 4 (CH 3 ) 3 SiOSO 2 , is characterized. In this reaction oxygen is transferred to silicon and sulfur from sulfur dioxide, but Si-N bonding is still partially retained. The solid product, ammonium trimethylsilyl sulfite, sublimes readily at ambient temperature but exhibits ionic properties. The variety of products and the overall reaction stoichiometry impose severe restrictions on possible reaction mechanisms. These constraints are discussed, and a consistent reaction scheme is proposed for this facile but unusual reaction. © 1982, American Chemical Society. All rights reserved.
