α-Benzyl aldehydes are prepared from easily available β-silylalkenals and fluoride reagents, under mild experimental conditions; the reaction occurs instantaneously with almost quantitative yields. A plausible mechanism is suggested, which involves a 1,2-phenyl migration from the silicon to the adjacent carbon atom.
在温和的实验条件下,由容易获得的β-甲硅烷基烯酮和氟化物试剂制得α-苄基醛。该反应瞬间发生,收率几乎定量。提出了一种可能的机理,该机理涉及1,2-苯基从硅迁移到相邻的碳原子。
