Ethyl 3,3-difluoro-2-methylpropenoate forms 1 : 1 adducts with tetrahydrofuran and 1,3-dioxolanes under free radical conditions. In contrast no 1 : 1 adducts are observed when tetrahydropyran and 1,3-dioxanes are used as sources of α-alkoxy radicals. An explanation is presented based on FMO and radical stability arguments.
3,3-二氟-2-甲基丙酸乙酯在自由基条件下与四氢呋喃和1,3-二氧戊环形成1:1加合物。相反,当将四氢吡喃和1,3-二恶烷用作α-烷氧基的来源时,没有观察到1:1的加合物。基于FMO和基本稳定性论证进行了解释。
