 Title    Silyl-Assistierte Etherspaltung bei Radikalkationen von Hydroxylaminderivaten [1] Silyl-Assisted Ether Cleavage in Radical Cations of Hydroxylamine Derivatives [1]  
 Abstract    It is demonstrad by means of various mass spectrometric techniques that the dissociative ionization of N.N-bis-silylated hydroxylamine derivatives (5 a) and (5 b), giving rise to the cleavage of the (O-C) bond, is anchimerically assisted by migration of the trimethylsilyl group to the ether oxygen, thus generating ion (7).

 Abstract    Kinetic energy release measurements dem-onstrate that the loss of neutral HN, Et0C(0)N from the compounds investigated seems to occur by a symmetry allowed (1,1) elimination. lionized nitrenes are produced with only very low intensity.
