Synthesis, Properties, and Crystal Structure of Silyl Nitronates (Silyl Esters of aci‐Nitroalkanes): Towards the SN2 Reaction Path with Retention of Configuration at Silicon
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 N 2 retention pathway at silicon.
