We report a stereoselective route to synthesize (E)-2-bromo-2-fluoro-1-(2,4,6-tri-t-butylphenyl)-2-phosphaethene. Configurationally and conformationally controlled 2-fluoro-1-phosphaethene [Mes*PC(F)H; Mes* = 2,4,6-tBu3C6H2] and 2-fluoro-1,3-diphosphapropene [Mes*PC(F)-PPh2] were synthesized and the NMR data, including relaxation parameters, were collected.
我们报道了合成(E)-2-溴-2-氟-1-(2,4,6-三叔丁基苯基)-2-磷乙烯的立体选择性路线。构型和构象受控的2-氟-1-磷乙烯[Mes*PC(F)H;合成了 Mes* = 2,4,6-tBu3C6H2] 和 2-氟-1,3-二磷丙烯 [Mes*PC(F)-PPh2],并收集了 NMR 数据,包括弛豫参数。
