资源简介：
To investigate the intramolecular 1,5-type C-···Si
interaction, (2-(trimethylsilyl)phenyl)phosphonium methylides 1
were prepared. Treatment of the precursors, the methyl(2-(trimethylsilyl)phenyl)phosphonium iodides 2 (R = Ph, Me), with
sodium hexamethyldisilazide in THF afforded the phosphonium
methylides 1, which readily underwent anionic 1,4-silyl migration to form the silylated ylides 4 at low temperatures. They
were characterized by NMR and trapping experiments.
