Abstract

Abstract Attack of the oxyl (CF 3) 2 NO·(1) on an ethyl group of the silane Et 2 SiCl 2 occurs at both the α-and β-positions relative to silicon (ratio 31: 45), whereas with the silane Pr n SiMeCl 2 attack takes place at the β-position of the propyl group. With the disilane Me 3 SiCH 2 SiMe 3, the major silicon-containing products formed from treatment with oxyl 1 are Me 3 SiF,(CF 3) 2 NOSiMe 3 and Me 3 SiSiMe 3. Speier-catalysed (H 2 PtCl 6) addition of ...
