- 中文摘要: The photolytic reactions of 2-substituted allyl chloride with t-BuHgCl in different solvents were investigated. The reactions proceed the SH2' reaction mechanism except the substituent is a strong electron-releasing group. The electron transfer process becomes more competitive with the radical addition process when the substituent is a strong electron-releasing group. When the substituent is a strong electron-releasing group such as -CH2SiMe3, the reaction in CH3CN shows pronounced electron transfer process while the reaction in DMSO or THF involves both of the SH2' and the electron transfer processes. The reaction is solvent dependent. An electron transfer mechanism is discussed.
