O-Trialkylsilylation

Anionic 1,4-silyl migrations of O-trialkylsilyl methyl ketoximes (268) were found to give o -trialkylsilyl ketoximes 269 after hydrolysis (equation 167). Intramolecularity of this migration was confirmed by crossover experiments. Upon heating 269 at 100 °C, a reverse migration to 268 took place. The reaction appeared to be limited to silyl ethers of methyl ketoximes having the (E)-configuration413. [Pg.925]

The l-(ferf-butyldimethylsilyl)bicyclobutonium ion 115 generated in a similar way undergoes fast 1,3-hydride shift upon increasing the temperature to yield 3-ent/o-(iert-butyldimethylsilyl)bicyclobutonium ion 116 [Eq. (5.16)]. Ion 116 has a static structure, which is due to the efficient stabilization by the y-ent/o-trialkylsilyl substituent. [Pg.227]
