Abstract: Tris (organosi1yl) hydroxylamines when heated undergo a reversible 1, 2 rearrangement of organosilicon groups between oxygen and nitrogen. The rearrangement was studied by NMR at temperatures ranging from 139 to 162 OC. Kinetic data and activation parameters obtained indicate that the rearrangement is probably occurring by a type 1 dyotropic process, involving a four-centered transition state. Preparation and ...
