p-Tolyl benzeneselenosulfonate regioselectively added to the conjugate enynesulfones 1–9 gave (1E,3E)-1,4-bis(arylsulfonyl)-1,3-butadienes 10–17, which were converted to the 4-hetero atom-substituted-1-phenylsulfonyl-1,3-butadienes 18, 21 and 22.
将对甲苯苯硒磺酸盐区域选择性地添加到共轭烯炔砜1–9中,得到(1 E,3 E)-1,4-双(芳基磺酰基)-1,3-丁二烯10-17,它们被转化为4-杂原子-取代基-1-苯基磺酰基-1,3-丁二烯18,21和22。
