The allylsilanes (1), containing suitably-substituted hydroxy-groups, on treatment with iodosylbenzene in the presence of BF3–Et2O in an ether solvent, give 5- or 6-membered β-methylene cyclic ehters (3) in good yields, presumably via the highly reactive alylaryliodonium intermediates (2).
在醚溶剂中,在BF 3 -Et 2 O存在下,用碘基苯处理后,含有适当取代的羟基的烯丙基硅烷(1)可以得到5或6元的β-亚甲基环状酯(3)可能通过高反应性的芳基芳基碘鎓中间体(2)产生。
