The radical-mediated addition of triphenylphosphonium tetrafluoroborate to olefins (hydrophosphonation) is reported. Both standard radical initiators and photochemical conditions are effective, up to the gram scale. The phosphonium salts are shown to serve as Z-selective Wittig olefination reagents, even without purification.
据报道,自由基介导的四氟硼酸三苯基phosph加成到烯烃中(氢膦化作用)。标准的自由基引发剂和光化学条件均有效,直至克级。所示的salts盐即使不纯化也可用作Z-选择性维蒂希烯化剂。
