摘要：

An efficient and flexible method for the preparation of silyl nitronates is described (see 1–10). NMR. spectral investigations indicate a rapid 1,3-silyl migration process, with an activation energy of about 10 kcal mol⁻¹. X-ray crystallographic studies on the silyl nitronates 3 and 8 show structures that lean towards an S_N2 retention pathway at silicon.
