Abstract: Tris (organosily1) hydroxylamines undergo a general, intramolecular rearrangement at temperatures of 180 OC and above to give silylaminosiloxanes with high product selectivity. An organosilyl group bound to nitrogen appears to insert into the N-0 bond (see eq 1 in text). The reactions follow first-order kinetics over at least 4 half-lives with t1/2 at 205" Cas follows:(Me3Si) zNOSiMe3 (l), 5800;(Me3Si) zNOSiMe2-tB~(ll), 3600;( ...
